6 + (5 + 8) x 4 = 66 Is this correct? If not correct it. When you say your answer out loud, you must tell me HOW you got this answer.

No. The answer is 58. First, I solved the parentheses. Then, I solved the multiplication. Then, I solved the addition. 6 + (13) x 4 6 + (13 x 4) 6+ (52) 6+ 52 = 58

400

Is this correct? (10 x 2) ÷ (4 + 1) = 4 Show how you got your answer.

Yes it is correct. 20 ÷ (4 + 1) 20 ÷ 5 = 4

When given this problem: 7 x 7 + (13 - 4 ) + 7^2 What should I do first?

The 13 - 4 in the parentheses.

200

When given this problem: 7 x 7 - (8 - 2) What should I do first?

Solve (8 - 2) in parentheses.

300

Where should I put the parentheses to make this statement true? 10 ÷ 2 - 3 + 1 = 3

Around the 10 ÷ 2. This will make it 5 - 3 = 2 + 1 = 3

400

When given this problem: 9^4 + (12 x 4) - 17 What should I do first?

Solve for 12 x 4 because it is in parentheses.

500

Tell me how to solve this problem by telling me what to do first, second, third, etc. (29 - 18) + 14 ÷ 2 + 4^2

First, you solve (29 - 18) because it is in parentheses. Second, you solve 4^2 because it is an exponent. Third, you divide 14 ÷ 2 because it is division. Fourth, you add from left to right.
