How do you simplify #7(5  2) + 4 ÷ 2 times 2 +1# using order of operations?
Use PEMDAS (with caution!!!)
It would be incorrect to divide 4 by (2*2), since there was not originally a set of parentheses there. PEMDAS is a little misleading, since you actually have to multiply and divide at the same time (if there is not a set of parentheses).

To simplify the expression following the order of operations (PEMDAS/BODMAS), proceed as follows:

First, perform operations inside parentheses: (5  2 = 3)

Next, perform multiplication and division from left to right: (4 ÷ 2 = 2)

Then, continue with the multiplication: (2 \times 2 = 4)

Now, perform addition and subtraction from left to right: (7 \times 3 = 21) (21 + 4 = 25) (25 + 1 = 26)
So, the simplified expression is (26).

When evaluating a onesided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
