How do you make 19+3x15/2-3 adding parentheses brackets and braces

Answer 1

Two rules apply here:

1) Multiplication and addition have priority over addition and subtraction and

2) Operations are performed from left to right

19 + 3x15/2 -3

Take care of multiplication and division first going from left to right

19 + [(3x15)/2] - 3 =

19 + 45/2 - 3 =

19 + 22 1/2 - 3 =

41 1/2 - 3 = 38 1/2
