This sheet presumes making number into 10 helps make adding easier

2. 8 + 5 =

10 + 3 = 13 we get 3 by taking 2 from 5 and giving it to the 8 to get 10

3. 8 + 6 =

10 + 4 = 14 take 2 from 6 to give to 8 to make 10

I suspect the purpose of this is to promote mental math

Answer:

I'm going to explain this by doing number 2.

Step-by-step explanation:

Okay, so 8 is 2 away from 10. So we subtract 2 from 5, leaving 3. We add the 2 to the 8, making 10. Now, we add the other 3. 10+3=13. 8+5=13.

Answer:

1) Variables = 11a , 4a

Constants = 0

Coefficients = 11 , 4

2) Variables = 3x , 7x

Constants = 6 , -4

Coefficients = 3 , 7 , 6 , -4

3) Variables = -12m , +4m

Constants = -3 , 16

Coefficients = -12 , 4 , -3 , 16

4) Variables = 6k , k

Constants = -4 , -2

Coefficients = 6 , 1 , -4 , -2

5) Variables = -5p , -2p

Constants = 3 , 13

Coefficients = -5 , -2 , 3 , 13

6) Variables = -10r , -r , -6r

Constants = 11

Coefficients = -10 , -1 , -6 , 11

7) Variables = -5n

Constants = 19 , -8 , 14

Coefficients = -5 , 19 , -8 , 14

8) Variables = 13y , -2y

Constants = 18 , -5

Coefficients = 13 , -2 , 18 , -5

9) Variables = 8a , 3a , -7b , -2b

Constants = 1

Coefficients = 8 , 3 , -7 , -2 , 1

10) Variables = 11x , 2x , -4y

Constants = 8

Coefficients = 11 , 2 , -4 , 8
