Who on earth...?

I cannot imagine the person who buys these:



People who aren't maths geeks aren't going to want them. And people like me would actually be moved to smash them to pieces. I suppose you might buy one for a maths geek you don't really like, just to watch them squirm.

If I were a math geek and wanted a math cup I would much prefer something that was fun or symbolic or a famous quotation, not this. Maybe it's cool for kids in primary school? Maybe the guys who made it never made it past secondary school or something?

Trust me, if you were a maths geek, you wouldn't be wanting this. It's not cool for kids in primary school. Nor is to do with the education of those who made it (as you can tell from the name of the mug in the Etsy shop).

Just, WRONG!!!!!

Husband is away, so can you tell me exactly why it's wrong? On second thoughts, I could soften him up with this question to display his superiority, before I confess to having scraped the car today to the tune of £400 whilst having an I'm-so-tired-my-spatial-awareness-has-disappeared moment.

Oh dear, I'm sorry about the car. Parking when tired is always a bad idea.

The answer is x2+x-2, not +2x. Which is why I thought it might be fun for younger kids as they could feel great spotting what's wrong. I must be way too tired, because I don't find anything funny about this mug at all. Even if it's deliberate.

You have to multiply both terms in each bracket with both terms in the other bracket.

So it's:

x by x = x^2
x by -1 = -x
2 by x = 2x
2 by -1 = -2

The second and third terms can be combined to give: x^2 + x -2
