How to solve (2x5)x 5-(50-15)

(2x5)x 5-(50-15)is it 300?

10 * 5-(35)
10* -30????

Always do sums in brackets first so,

2x5=10
50-15=35
So...10x5=50
50-35=15 :) Hope i helped

Do you remember BIDMAS which is brackets, indices, division, multiplication, addition and subtraction. This is the order you need to approach the equation.
So (2X5)X5-(50-15) is
(10)X5-(35)
Which is 50 -35 = 15
Therefore the answer is 15.

I got -15.
(2x5)=10 x 5 = 50 -(50-15) = -15?

you have to do it in the order it's written don't you? else you don't get the correct answer?
hope it helped :S

2 x 5=10
50 - 15=35
5 - 35 = -30
10 x -30 = -300

50-35 = 15
