Simplify: 4 + 3 times 7.

A25
B49
C21
D28
Answer & Solution
Correct answer: A. 25
1. Check for parentheses or exponents in 4 + 3 times 7: there are none. 2. Multiplication and division come next, so multiply 3 times 7 to get 21. 3. Finish with addition: 4 plus 21 equals 25. 4. Adding 4 and 3 first, before multiplying, is the classic order of operations mistake that gives the wrong total of 49. _Source: OpenStax Elementary Algebra (CC BY 4.0), Ch 1 "Foundations", section 1.2 Use the Language of Algebra_
