Answer 1

To solve this problem, we need to follow the order of operations (PEMDAS) which stands for Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction.

First, we need to perform the multiplication.

11*90 = 990

Next, we add 5 to 990:

990+5 = 995

Finally, we subtract 20 from 995:

995-20 = 975

Therefore, the solution is 975

In summary, we first multiplied 11 and 90, then added 5 to the result, and finally subtracted 20. This is why the order of operations is important because it determines the order in which we perform the calculations in the equation.
