High School Placement Test (HSPT) Practice Test

To find the result of the expression 15 - 4 + 2, you should follow the order of operations as usual, which in this case is simply performing the operations from left to right since they are all addition and subtraction.

First, subtract 4 from 15. This gives you 11:

15 - 4 = 11

Next, add 2 to the result obtained:

11 + 2 = 13

Thus, the final answer is 13, which means the reasoning that led to this result is solid. The correct operations and the sequence in which they were executed yield a clear conclusion that 15 - 4 + 2 equals 13.
