How can we simplify the expression 17 – 6 × 10 + 2 – 12?

by

To simplify the expression 17 – 6 × 10 + 2 – 12, we’ll follow the order of operations, which is often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right).

  1. First, identify any multiplication in the expression. In this case, we have 6 × 10.
  2. Perform the multiplication:
    • 6 × 10 = 60
  3. Now substitute this back into the expression:
    • 17 – 60 + 2 – 12
  4. Next, proceed with addition and subtraction from left to right:
    • Start with 17 – 60: which equals -43.
    • Then add 2: -43 + 2 = -41.
    • Finally, subtract 12: -41 – 12 = -53.

Thus, the simplified result of the expression 17 – 6 × 10 + 2 – 12 is:

-53
