What is the difference between a numerical expression and an algebraic expression?

In the following expression, what number do you think belongs in the box? 8 + 4 =  + 5

True or False 4  3 + 2 = 14 6  7 = 42 8 + 2  5 = 12 3 + 7 = 7 + 3 9 = 3  3 6 = 6

Open Sentences 5  6 =  32 ÷  = 8 4 + 5 =  - 1 4  7 = 7   7 -  = 6 - 4  = 10 - 1  + 14 = 14 + 9

True or False 674 - 389 = 664 - 379 5  84 = 10  42 37  54 = 38  53 64 ÷ 14 = 32 ÷ 28

More Open Sentences 73 + 56 = 71 +  126 - 37 =  - 40 20  48 =   24 68 + 58 = 57 + 69 +
