I already answered one of these problems for you.
What do you think these answers are? I'll be glad to check them for you.
I already gave a link to communative property explanation down below
To find the missing numbers, let's solve each equation step by step:
1. 4 + 2 + 6 = _____
To find the missing number, add the numbers on the left side of the equation together:
4 + 2 + 6 = 12
Therefore, the missing number is 12.
2. 7 + 9 = _____ + 7
To find the missing number, subtract 7 from both sides of the equation:
(7 + 9) - 7 = _____
16 - 7 = _____
Therefore, the missing number is 9.
3. 3 + 5 + 3 = _____ + 5
To find the missing number, subtract 5 from both sides of the equation:
(3 + 5 + 3) - 5 = _____
11 - 5 = _____
Therefore, the missing number is 6.
