Question

How can you write 72+(8+19) to make it easier to add

Answer 1

72+8+19, take out the parenthesis.
You first can just do the simple, 72+8=80
So now you can just do 18+19=99
Does this help?

Answer 2

There's a key problem in this question compelling you to actually rewrite it like that! Mathematically that is inaccurate and incorrect. If you do 72(8+19) it seems as if you are going to do 8+19*72 as in algebra whatever is outside the bracket is bound to go multiplied so technically (8+19)+72 would make more sense and the answer is

Using bidmas do the brackets first

8+19= 27
27+72=99
