Whatever though, it doesn't matter - Who needs math? When was the last time you had to "solve for x"?

Back in high school which was about 15 years ago
From the Common Core Grade 1 Addition and Subtraction
Quote:
CCSS.Math.Content.1.OA.B.3
Apply properties of operations as strategies to add and subtract.2 Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
