Once upon a tragic math class, there was a 

young student named Kevin.   He, along with all 

his other classmates, was about to get their 

order of operations quiz back.   When Kevin 

got it back he froze in shock.   He got a 50%!  

He had never gotten such a low grade before 

in his life. He was a straight A student, he did 

not have any idea what he did wrong.

Kevin went up to the 

teacher and asked what 

he did wrong that made 

him receive a 50%.   She 

looked at his work for 

the problems he got 

wrong and said, "Kevin, 

you did PEMDAS, but you 

may not realize that 

there is a tricky 

exception to PEMDAS.

"How could that be possible, that's what you taught 

us," Kevin stated.  

"Yes, I did teach you PEMDAS, but when you do 

PEMDAS, you have to remember in some situations  

M does not come before D.   It's the same for 

addition and subtraction. If the division sign comes 

before the multiplication sign or the subtraction 

sign comes before the addition sign then you go 

from left to right."   

Kevin wasn't sure this made sense. So the teacher 

gave him an example.

"This is the first problem, I will help you through 

it."

4 / 2*(7-4)*8 to the power of 2+13=

"The first thing you would do in this kind of 

problem is figure out the problem in the 

parenthesis. In this equation, the answer would 

be 3. Then you would find the exponent. In this 

problem the exponent is 8 to the second power, so 

the answer would be 64." 

"Next, you would do 4/2. The answer is 2, and you 

should bring it down to the next line. Try to finish 

the rest of the problem on your own. Remember, 

move from left to right when dealing with 

multiplication, division, addition and subtraction."

This is my work....

4/2*3*8 to the power of 2+13

4/2*3*64+13

2*3*64+13

6*64+13

"Now try this, all by yourself!"

6/2*8-(5 to the second power) + 703
