Then do exponents: x Then do Multiplication or Division operations from left to right. Last do Addition or Subtraction operations from left to right |

order of operations
example problem: 3 + 5 * 7 / (8 - 7)
In this case, you need to do the 8 - 7 first since it’s in parentheses, then the 5 * 7, and
the result should be divided by the 1 from the parentheses operation then add to the
three. So it goes like this:
the result should be divided by the 1 from the parentheses operation then add to the
three. So it goes like this:
3 + 5 * 7 / 1
3 + 35 / 1
3 + 35
3 + 35 / 1
3 + 35
The answer for the above problem is 38.
