To simplify this expression, we must make use of the PEMDAS
Rule. The PEMDAS Rule (Parenthesis, Exponent, Multiplication or Division,
Addition or Subtraction) states that when doing mathematical operations, the
factor inside the in the Parenthesis must be solved first followed by the
exponent and then multiplication or division (depending on which is first),
addition or subtraction (depending on which is first).
So in this case we can see that there is no parenthesis and
exponent. So we do the multiplication first, so the expression becomes:
8 – 3 + 5
Then followed by the subtraction:
5 + 5
Then finally addition:
10
