+12
You need to add 7 (or +7)
you need to add +9 +9-7 = +2
You add 10 to -7 to get 3.
nine add 7 to get from -7 to 0 then add 2 to get to 2 7 + 2 = 9
+12
Ah, what a delightful question! To find the perimeter of a grid, you simply add up all the sides. In this case, with a grid of 7 by 5, you would add 7 + 7 + 5 + 5, which equals 24 units. Just imagine all the happy little lines coming together to create a beautiful border!
You add 7 -5 + 7 = 2
To get 1, you need 12 twelfths. If you have 7/12 you have to add 5/12 to get to 12/12 = 1(7 + 5 = 12, 7/12 + 5/12 = 12/12 = 1)

You can, if you have a square with side 5 you can multiply 5*5=25 or you can add 5+5+5+5+5=25 If you want to do this just take one of the numbers and add it to itself the other numbers times. so if you have 7*8 you add 7 to itself 8 times, so add 8 7's 7+7+7+7+7+7+7+7=56 or add 7 8's 8+8+8+8+8+8+8=56 Multiplying is much easier.
nine add 7 to get from -7 to 0 then add 2 to get to 2 7 + 2 = 9
