Simplify the expression. (Remember the order of operations.) See Examples.

Example Simplify the expression.
a. −14 − 8 + 10 − (−6)
b. 1.6 − (−10.3) + (−5.6)
Solution:
a. −14 − 8 + 10 − (−6) = −14 + (−8) + 10 + 6 = −6
b. 1.6 − (−10.3) + (−5.6) = 1.6 + 10.3 + (−5.6) = 6.3
Example Simplify the expression.
a. −3 + [(−2 − 5) − 2]
b. 23 − 10 + [−6 − (−5)]
Solution:
a. Start with the innermost set of parentheses. Rewrite −2 − 5 as an addition.
b. Start simplifying the expression inside the brackets by writing −6 − (−5) as an addition.
