Mr. R.’s World of Math

A miserable martian,
Tried to subtract,
But got every answer all wrong,

2- (-2)

Why was it hard to do the math problems?
Why were her faces so long?
(this martian had 2 faces)
The problem was clear,
She’d try to subtract,
All Integers the same exact way,
And that’s the whole reason she got them all wrong,
That is what led her astray…

7 – (-8)

She really should know, this one little rule,
For negative number subtraction:
Change both signs to read positive,
For positive math time reaction…
