how smart are you, part 2?

15, but i used a calculator…

18. No one said using a calculator was against the rules.

Assuming you are allowed to use a calculator (the lottery one... without a calc? No thanks, I have to do *some* work today too!) then I got a nice full 20.

I quite enjoyed that in a 'oh-my-God-how-much-can-I-remember-from-School' sort of way.

20/20

My maths is clearly better than my grammar...

 

[Paulus]

10/20 for me. No better than when I was at school. I was average then.

18/20

I haven't simplified an equation in a very long time, and I have no idea what factors are
I did well at maths at school, despite never understanding most of it

 

[bonk man]

14 in the English and 12 in the maths but I did guess a couple of those

19, but in a hurry so used a calculator.. Is that cheating?

 

[GilesM]

18/20, couldn't remember the stuff about factors, but it was probably close to 30 years when I did that at school, and not exactly something you use in your everyday life, anyone who got the 3, 4, 5 triangle wrong should be shot.

But did you glance and just think 'Pythagoras' it's got to be 5... or did you calculate it and then realise it was the old 3,4,5 triangle?

I just knew...

Using a calculator is ok, I reckon - the point is, you have to know what to do with it, or it's no more use than a lime jelly.

 

[Bokonon]

If you know what all the operators used in the questions are and how to apply them, recognise common numbers like squares or pythagorean triples, and know a few basic 'tricks' like how to recognise a multiple of 9 then none of the questions require the use of a calculator. The questions that look quite tricky to start with, like the lottery one, are actually quite easy to solve (test the given answers, rather than try to solve.) The only questions that require any complete calculations are the more simple ones.

9/20.. could do better

No Pythagoras needed, no calculation either, the 3, 4, 5 triangle is the basis of so much, the easy way to make a perfect right angle, now if the two sides had been 6 and 8, then it would have taken a few seconds for it to click and I might have got as far as adding a few squares together before I realised.

- although I am not sure the answer to the tennis ball question is correct. For me it was fifty years ago but we had better teachers then. If you drifted off you'd be woken up by a book in your face and a short burst of sarcasm which brought forth howls of glee from your classmates, somewhat mollifying Sir.
