Question

325(324-323) can you help me solve this problem

Answer 1

So you do the parentheses first.
324-323 = 1.
Since there is no sign by the parentheses and the other number you multiply.
1 x 325 = 325
So your answer is 325

Answer 2

You can use BODMAS, it is a acronym that stands for: brackets, orders, division, multiplication, addition, subtraction. This is a general order to see what parts of a equation you solve;

We can see there is a bracket, so we solve that first;
(324-323) = 1

Then numbers next to brackets just means we multiply them, so...
325(1) = 325*1 = 325

Hope this helps! :)
