Answer 3

To calculate the given expressions, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's evaluate the expressions step by step:

1. (400-816:3)*7

Step 1: Perform the division inside the parentheses. 816 ÷ 3 = 272

Step 2: Perform the subtraction inside the parentheses. 400 - 272 = 128

Step 3: Multiply the result by 7. 128 * 7 = 896

The result of the first expression is 896.

2. 167*4+756:7

Step 1: Perform the multiplication. 167 * 4 = 668

Step 2: Perform the division. 756 ÷ 7 = 108

Step 3: Perform the addition. 668 + 108 = 776

The result of the second expression is 776.

So, the final answers are:

1. (400-816:3)*7 = 896
2. 167*4+756:7 = 776
