What is #4\cdot 2- 3( 2- 5) + 6\div 2#?
The answer is
P stands for Parenthesis so Parenthesis must be done first.
There are no exponents so go on to MD
MD stands for Multiplication and Division. Think Medical Doctor=MD
A Medical Doctor is one person not two. MD must be done together, can't cut the doctor in half. So we must work from left to right doing all the multiplication and division before doing any addition or subtraction.
( a negative times a negative equals a positive.)
Think: a negative is something bad. A negative is the sign for subtraction, or to take away. So to take away something bad is good. Good is positive.
Add them from left to right
Remember if you get hurt in PE call an MD Asap
Always count the number of terms first. Each term will simplify to a single number. Keep them separate until the last line where you will add or subtract to get the final answer.
You can calculate within each term in a line.
Within each term the order of operations applies, do brackets first, then from strongest to weakest:
Powers and Roots, then Multiply and Divide
Last: Add and Subtract.
