Question Use the descriptive property to evaluate the expression
4 x (80 + 3)
Answer Hello, Jasmine.
According to the order of operations, evaluation of parentheses comes before multiplication. Therefore, for this problem, 80 + 3 is first evaluated, which equals 83.
83 is then multiplied by 4, which gives an answer of 332.
