Question

Tyson says the value of the expression 6 + 9 ÷ 3 × 7 is 35. Part A What is the first step in evaluating the expression? A. Add 6 and 9. B. Divide 9 by 3. C. Multiply 3 by 7. D. Add 6 and 3. Part B What is the second step in evaluating the expression? A. Add 6 and 3. B. Divide 15 by 3. C. Multiply 3 by 7. D. Multiply 9 by 7. Part C Did Tyson use the order of operations to correctly evaluate the expression? Use the drop-down menus to show your answer. ; the value of the expression is

Answer 1

part A : A

part B :B

part C :No,

27

Explanation:

BODMAS

6+9/3*7

according to the order of operations,

division comes before multiplication and addition

so we first divide 9 by 3 then multiply the answer by 7 and finally add the result to 6

Therefore the answer is 27

Answer 2

Part A- (B) Divide 9 by 3

Part B- (C) Multiply 3 by 7

Part C- Tyson is wrong, because we found that the value of the expression was 27. Tyson must have solved the expression the way it was written from left to right and did not follow order of operations (PEMDAS).

*The value of this expression= 27.*

Explanation:

Beware, we do NOT solve in the order the number sentence is given. By PEMDAS- first we solve Parenthesis (if any) , next we solve Exponents (if any), then we solve the Multiplication or Division based on whichever is first from the left, finally we solve Addition or Subtraction based on whichever appears first from the left, we solve first. So, following PEMDAS, there are no Parenthesis nor Exponents in your number sentence- the next step would be Multiplication or Division. So, which operation comes first from the left in your expression, between Multiplication or Division? Division, so we solve that, 9/3, which is 3. We rewrite the expression with the new answer- 6+ 3 x 7. Ok, so are there any more Division or Multiplication to solve so that we can move to the next step? Yes. 3 x 7, which is 21. We rewrite the expression again, 6+21, and the final answer is .....27. Therefore, going back in the process, remember the first operation we did and that is? DIVISION. Also, that means Tyson is wrong, because we found that the value was 27. Tyson must have solved the expression the way it was written from left to right and did not follow order of operations (PEMDAS).
