I'm using A1, A2 and A3 to show a generic question.
A1 - A2(- A3)
I forgot about the negative sign inside the bracket and expanded it in the form:
A1 - A2(A3)
Careless error :mad: :mad: :mad:

I wrote 1 x 3 = 1.
When asked to find f(0), after finding a pronumeral within that function, I...forgot to sub in x.
In an AP question, I found a. But when finding the term asked, I forgot to sub in a, only d.
I often forget the second number in evaluating a definite integral.
Yet we know I'm not bad at maths, because I rank in the top 20 at NSG.

You cannot possibly beat my carelessness in maths.

In my last 3 unit exam, the only mark I lost was because I forgot to write +- when I square rooted something

1+1=3.
Worst of all, it was a long division question and it took me about 20 minutes to find out why my polynomial wasn't factorising. :mad:

Not taking the negative case when you do the square root is annoying.

Oh GOD this thread is exactly what I needed!!!


In this year's half yearly... I lost 2 marks because of:

2+3=6

1/0=1


I can never avoid making at least one of those dumb mistakes in a maths exam :(
