What is #7 - 25 + 6 -: 2 xx 25#? #color(white)("mmm")# Edited by Tony B:#color(white)(..)#Changed 2 star 25 for multiply to 2 x 25
The answer is
Let's use the PEMDAS method.
If there are operations with the same priority (multiplication and division or addition and substraction) you calculate them from left to right so:
Now we have only addition and substraction so we calculate them from left to right:

Identify the number of terms first. Reduce each term to a single answer by following the order of operation from strongest to weakest within each term. Brackets must be done first., then
powers and roots, then multiplication and division.
Last addition and subtraction.
It is safer to re-arrange the terms to have all the additions first. Many errors are made if subtractions are done first.

To solve the expression (7 - 25 + \frac{6}{2} \times 25), follow the order of operations (PEMDAS/BODMAS):
-
Perform division and multiplication from left to right: [6 \div 2 = 3] [3 \times 25 = 75]
-
Now, perform addition and subtraction from left to right: [7 - 25 + 75]
-
Perform the remaining operations: [7 - 25 = -18] [-18 + 75 = 57]
Therefore, (7 - 25 + \frac{6}{2} \times 25 = 57).

When evaluating a one-sided 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.
