Answer 2

To evaluate these expressions, let's follow the order of operations (also known as PEMDAS/BODMAS) which stands for Parentheses/Brackets, Exponents/Orders, Multiplication/Division, and Addition/Subtraction.

1. 17 + 43 ÷ 12.15 - 35 × 11 ÷ 2

We'll first perform the multiplication and division from left to right: = 17 + (43 ÷ 12.15) - (35 × 11 ÷ 2) = 17 + (3.539) - (385 ÷ 2)

Now, we'll perform the remaining additions and subtractions: = 17 + 3.539 - 192.5 = 20.539 - 192.5 = -171.961

Therefore, the result of the expression is approximately -171.961.

2. 80 - 26 ÷ 18 + 97 - 36 × 3

Again, we'll perform the multiplication and division from left to right: = 80 - (26 ÷ 18) + 97 - (36 × 3) = 80 - (1.444) + 97 - (108)

Now, we'll perform the remaining additions and subtractions: = 80 - 1.444 + 97 - 108 = 79.556 + 97 - 108 = 176.556 - 108 = 68.556

Therefore, the result of the expression is approximately 68.556.
