8[(5-2)(6+4)] We use distributive property first You will have (40-16)(48+32) (24)(80) 24 x 80 is equals to 1,920 =1,920

If you will going to manipulate that in a scientific calculator it will not arrive in 1, 920. Therefore thats wrong. You have wrong process in solving it

We will going to operate numbers inside the bracket first before going out to the constant outside of it. 8 will going to multiply to the product of sum and difference of nos. inside the parenthesis. We will not going to distribute that one by one thats wrong.
