The Dumbest mistake u've ever made in a Maths Exam (4 Viewers)

[*TRUE*]

sine = hypotenuse over adjacent for something. Got it all wrong.

i love the adage; silly old hags cant always hide their old age. simple and brilliant.

i once left out 1/4 of a 3 unit exam which was on the back page; happy that was in the prelim course.

This happened in my 2unit exam 2 weeks ago:

22x = 11
x = 2

RAGE!! It was for simultaneous equations too, so you can bet that y was wrong as well

That's why you have to check your answers at the end.

I know .. I feel so beat up about it.

Anddd... I also completed a perfect square leaving the equation like this:

3x^2 + 8x -1 = 0

*sigh.

 

[ForbiddenND]

Lol... It was a multiple choice bit and they gave 4 options of only which 1 was obviously right because it the question was about the volume of a cube. All the answers has cm^2 except one which was cm^3. I spent like 5 mins out of the 10 mins for that section and I still got it wrong lol.

Accidentally skipping an easy 2 mark question

 

[nerdsforever]

sin60/tan30
= √3/2 x 1/√3
= 1/2

ARRRGGHHH!!! it was division!!!

--------------------------------------------------------

form equation with roots:
3 and -4

x^2 + x - 12

forgot the = 0. No marks

-----------------------------------------

factorise 28 + 3x - x^2

= (x-7) (x+4)

supposed to be - (x+7) (x+4)

 

[Patar]

Well, our old Maths teacher told us about this one, unfortunately its not mine but he's a HSC marker so...

Simplify:
1 mark

b^2 + b + 1
Divided by:
b + 1

and they would cancel out that

b^2 + b + 1
Divided by:
b + 1

to get b^2

It's enough to make you sick, isn't it? lol

Hmm the dumbest mistake ive ever made in a maths test was probably this year in my half yearly i was expanding brackets and i wrote 1*2 = 1 lol, u cant get any dumber than that!

1*2 does = 1

Lol, maybe the dumbest mistake he made was really multiplying it wrong, second-guessing himself then posting it publically on BOS

haha, kidding

 

[Aerath]

1*2 does = 1

I'm so lost. I swear I thought 1*2 = 2

 

[lyounamu]

1*2 does = 1

1*2 = 1 x 2 isn't it?

1^2 = 1 x 1

In year 11, after learning functions we had a short in class test where we had to sketch about 8 functions and state their domain and range. I completely overlooked the domain and range bit, so completely left it out, so ended up losing half the marks.

Thankfully it didnt count though

Same here except that it was in my Chemistry exam.

1*2 = 1x2 not 1²

oh shit my bad

 

[jockrussell]

lol yea it was 1 times 2. How do make the times symbol any1?

 

[Aerath]

Hahaha

Shift + 8 = *

 

[jockrussell]

lol im no that dumb, i meant how do u do the real times symbol.
1x2. That 1 but i didnt do it i just copied and pasted it lol.
