 * When you add two positive numbers, you can add normally (3+5=8; 5+3=8)
 * When you add a positive and a negative number, subtract the smaller number from the larger number. Whatever sign the larger number has is the sign the answer gets (-5+3=-2; -3+5=2)
 * When you add two negative numbers, add the numbers together and put a negative sign in front of your answer (-3+ -5=-8)
 * When you subtract two positive numbers and the first number is larger than the second, you can subtract normally (8-5=3; 8-3=5)
 * When you subtract a negative number and a positive number, OR when you subtract a larger number from a smaller number, switch the minus sign to a plus and make the second number opposite (a positive becomes a negative, a negative becomes a positive) then follow the steps above. (-3-5 becomes -3+-5=-8; -3 - -5 becomes -3+5=2; 3- -5 becomes 3+5=8; 3-5 becomes 3+ -5=-2)

Lyrics: When we begin we begin together Parenthesis first now please be clever Exponents come right next in line Now we multiply and divide at the same time Now subtraction and additionWalk it out with computation It's the order of operations

Please (parenthesis) Excuse (exponents) My (multiply) Dear (divide) Aunt (addition) Sally (subtraction)
