The “{“ is just the same as a “(“ bracket. The reason it is used is to tell it apart from the “(“ and not get the two confused. In this question you would do the stuff in the “( )” brackets first, then multiply the 10 by whatever is left in the “{“ brackets.
10{8(15-7)-(4x3)} = 10{8(8)-(12)} = 10{64-12} = 10{52} = 520
The answer is 520

The {} brackets mean multiplication, just as the () brackets. You just have to work out the what's in the () brackets before you go for the {} brackets.
ie. after you found the answer for 8(15-7)-(4x3), you should multiply it by 10.

the bracket is the same as writting in another set of parenthesis (). Its just a different way to group symbols and problems.
to sovle you start at the very beginning with 15-7 and 4x3. then subtract them, which equals -4. then multiply by 8. -4x8 = -32. -32x10 = -320

The bracket is used the same as parentheses. So as following the order of operations, you do whats inside the inner () first, then do whats in the {} , and then do the outside. So you do 15-7, then 4*3, multiply, subtract, then multiply.
This should help you figure it out. And show your work on your paper so if you do screw it up, you can see where you went wrong.

The bracket serves the same purpose as the parnthesis, it's telling you to multiply the 10 by the result in the barcket.

That encloses that whole operation with in the brackets. Do the work within the parenthesis first, then within the brackets.

the bracket, is like parenthesis, except means do it last, so you take whats in parenthesis, work it out, and then once you get whats inside the brackets tooken care of, you multiply by the outside number, 10.
520 is ur answer

brackets mean "perform this calculation first", the person has used two different sets of brackets to make the expression easier to read

{ is the same as ( ... they were trying to be different...stupid actually
it only means do this first...algebra basics...in-side-out.. i.e.
15-7=8 and 4x3=12 then 8x8=64-12=52x10=520...whew
