Order of operations tells us what order must be used when evaluating a numberical expressions with two or more operations.
The order is paranthesis then exponents then mutliplication or division, then addition or subtraction.
The mnemonic PEMDAS is an acronym commonly used to remember this.
Some people use the the phrase:
Please Excuse My Dear Aunt Sally to remember it.
Examples:
-22 the order tells us to to the exponent first so this is -4
but (-2)2 =4 because we take what is inside the paranthesis first.
1. 20-2(2+10)=
2. 20-2(12)=
3. 20-24= -4
IF you did 20-2 in line 2. , then you would have 18(12) and you would get the wrong answer!
wow impressive that is true........PEMDAS will tell you so much you just have to remember it please excuse my dear aunt sally
