The answer is 68. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.
12 + 23 + 45 + 67 + 16 + 18 + 45 = 226
If you mean 125+23+45 then it is 193
what plus what = 23
23 - 45 + 17 = -5
45 + 8 - 23 + 2 = 32
45
68
45
It doesn't, it should equal 45 again. I am unsure how you got this second answer but it is wrong
The answer is 45. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.
The answer is nine. Seriously. Here is my work if you don't believe me: 68=8x+23+4x-7x 68=8x-7x+23+4x 68=x+23+4x 68=x+4x+23 68=5x+23 68-23=5x 45=5x x=45/5 x=9
Assuming that there is a "plus" after the second 58, the answer is - the associative property of addition.
