Findings:

• "If I had to do it, I would already know how to do the math. But when I'm standing in the store, I have a hard time doing it." (TP 06, answer: with great difficulty)
• "If it is odd, it gets complicated, straight in the head. For example, if it's 27%, I need technical help.” (TP 07, answer: with certain difficulties)
• “At 50 %, 20 % or 10 % this is still possible, but as soon as 3 % of an odd number [should be calculated], it becomes more difficult. If I would calculate more often with a calculator and I would know how to do it in the calculator, it would be no problem. But I hardly ever do that.”(TP 10, answer: with great difficulties)
• "If you can write it down and calculate it with a calculator, then it works, but in your head like this.” (TP 12, answer: with certain difficulties)

Findings:

• "Length times width." (TP 02)
• "I also laid laminate myself in my apartment. You take length times width, how many square meters you need.” (TP 09)
• "I can definitely calculate the area of a wall. Length times width. A two-dimensional surface." (TP 16)
• "2.5 meters by 4 meters, that's relatively easy." (TP 19)

• "Multiply in your head, estimate and measure. That is no problem to calculate an area. Most of the time you have the formulas in your head and then you can easily calculate the area." (TP 08)
• "I have to know how many square meters. First in meters and then in square meters, then I have to add it up. Of course I can't calculate the number of plates, you have to tell the man where I buy [the plates].” (TP 11)

• "There I add up the 4 walls, so 3.5 x 4 m for wallpaper, for example." (TP 03)
• "Length times width would be easy, but as soon as a part has to be moved e.g. away from the heating, then I don't know how to subtract something from what." (TP 05)
• "Calculate a barrel or a circle." (TP 12)
• "I have the problem, I need the formula. There are people who can get it out of their heads, but I always need a formula." (TP 17)

Findings:

• "I immediately think of cooking or baking with American recipes, where everything is given in "cups”.” (TP 05)
• "First of all I think of measures of length, cm in dm and m etc." (TP 10)
• "If I measure something in the measuring cup, e.g. half a liter, then that is 50 cl and 500 ml. Or meters in kilometers." (TP 12)
• "Convert one pound of coffee. I prefer grams." (TP 13)

• "All those simple units from milli to micro or no idea what, yes, but from miles to kilometers that's something else. I'd have to look up, what is a mile." (TP 01)
• "Well, there are certain difficulties with miles and kilometers, because I would have to look it up first because I don't know. I'd have to know how long a mile is first." (TP 14)
• "I don't know now how to express miles in kilometers." (TP 19)

Findings:

• "Calculate three-sentence calculation in the same way as for fuel consumption. I do that occasionally in my head and it's easy for me.” (TP 04)
• "I think that's something you do more often. The contract has this and the other has that. I might not use one of them. Or I have free SMS. [...] For a short time I thought of a formula where different things are used one after the other, but you can't calculate that directly with the contract. You have different steps." (TP 06)
• "I do also always make that, if I must decide between two offers, that does not have to be al-ways a cell phone contract, then one goes also there and computes only times. For example also electricity providers. That I compare the fixed costs and also the variable costs and look at me, what I need and/or use. That can also be a multi-level comparison calculation." (TP 09)
• "I was thinking about some text tasks where you have to do several steps. First like this, then plus, minus and then a three-part sentence in the back." (TP 16)

• "It is not a multiple bill. You compare who offers the cheapest Allnet flat rate and has a good net and all that. Well, I'll manage that, I'll have to find the right cell phone contract.” (TP 10)
• "To the calculation from the telephone provider for me. 25€ and 9,95€ are a big difference for me.” (TP 11)
• "I was thinking about the cell phone contract. Per month, with Internet flat rate without Internet flat rate, i.e. the services per month." (TP 17)
• "You read it through. So and so much Flatrate for so much euro etc. and compare that." (TP 20)

Findings:

• "I know what it costs here, what it costs in Frankfurt, what it costs in Heidelberg. That is no problem. Frankfurt is expensive, Mannheim is cheaper, Heidelberg is in the middle." (TP 03, answer: I can without problems)
• "I have a house and know how many square meters that is, but the other one no. In the newspaper, I can understand that. Often there are certain square meters for apartment rentals. I understand that, but how much it should cost and how expensive the real estate agent is, I have never dealt with that." (TP 11, answer: I cannot)

• "We had this once in an Excel course with bar charts or something and I never knew what to get out of it, honestly." (TP 05)
• "This is again so that it is not commonplace. When you look at something like this, you first have to come in and understand what the axes mean and that's what I find the certain difficulties." (TP 08)
• "A coordinate system with an x and y axis and there you can see the development. I can also interpret it." (TP 09)
• TP 12: "I haven't done that yet. Maybe I could, I can't tell you."
• CI: "What if it was about a diagram in the newspaper?"
• TP 12:"I probably could. But I was thinking about big plans and calculations etc."
• "You'll have to get your head into it. Then there are circles. Then it says what costs what. But I don't deal with that in the same way." (TP 13)
• "I thought of a cake like this [pie chart]. I can read that." (TP 16)

Findings:

• "Because I had to work with illustrations and statistics for my final papers in my student days, or I had to create one myself. Then this goes along with the fact that I have to present information in illustrations." (TP 09)
• "I always enjoy doing that. Take stock of who has come to me in practice and I also create graphics myself." (TP 17)

• "I would have to deal with everything first. Think about it for a moment, but then it should work out." (TP 01, answer: certain difficulties)
• "I am missing an example here. I cannot answer, because there is no example to take away my fear. Then the question wouldn't be so bad either." (TP 10, Answer: great difficulties)
• "Too many tables and graphics. So I assumed directly that I couldn't do it." (TP 12, Answer: I cannot)
• "That sounds so complicated and that's something I don't really like to do. It sounds complicated and you really have to think about what is meant by that." (TP 16, Answer: certain difficulties)

• "For example, surveys in the university, you also have to present them in tabular form.” (TP 08)
• "For example, I was thinking about complex Excel spreadsheets." (TP 19)
