36 Addition Facts Flashcards
Addition rules 2
Commutative property : I can always switch the order of an addition problem.
E.g
if I know 3+7=10
Then I know too 7+3=10
Addition rules 3
Adding 1 is just counting up.
Eg.
2+1=3
Addition rules 4
Adding 10 is multi-digit addition.
When I add to a single-digit number, all I have to do is put a 1 in the tens place of the answer. The ones place digit will just be the single digit-number you added to 10.
Eg.
5+10=15
