Math Problem Statement

17 + 2 x 15 +7-23 =

Solution

Let's solve the expression step by step, following the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

Given expression:

17+2×15+72317 + 2 \times 15 + 7 - 23

  1. First, handle the multiplication: 2×15=302 \times 15 = 30 Now the expression becomes: 17+30+72317 + 30 + 7 - 23

  2. Next, perform the addition and subtraction from left to right: 17+30=4717 + 30 = 47 47+7=5447 + 7 = 54 5423=3154 - 23 = 31

Thus, the value of the expression is:

31\boxed{31}
