How do you find the value of #2+8(5)div2-3#?
PEMDAS The answer is
PE is parenthesis and exponents these must be done first.
MD is multiplication and Division these must be done next working from left to right
AS is addition and subtraction these must be done last again working from left to right.
A way to remember this is "if you get hurt in PE class call an MD (a medical doctor) ASap ( as soon as possible.)
The Medical Doctor (MD) is one person so the multiplication and Division must be done together.
ASAP (AS) is one time right now so the addition and subtraction must be done together.

In any calculation involving different operations, the MOST important thing is to count the number of TERMS first. Each term is kept separate until the last line, and then they are added or subtracted.
Within each term:
- brackets are done first, -then powers and roots, -then multiply and divide.
Carry each term down to the next line

To find the value of ( 2 + \frac{8 \times 5}{2} - 3 ), follow the order of operations, which is parentheses first, then multiplication/division from left to right, and finally addition/subtraction from left to right.

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.
