78 + yz = yz + 78

When you have an algebraic expression, the term is "reducing" the expression when you write the expression in fewer terms or smaller multiples.
You could write-9 + 24It's equivalent to 15.
The expression (a+b) + (a-b) can be rewritten as a + b + a - b = 2a.There is no need to use absolute value.
800 + 90 + 4 - 1 = 893
hi
30 -5 =x
The commutative property for addition is a + b = b + a
A - B = A + (-B) A - B = A + (-B) A - B = A + (-B) A - B = A + (-B)
7r = r + r + r + r + r + r + r or r7
467 + 1
The sum of b and 8 would be written b+8 or 8+b(commutative property of addition)
6000 + 100 + 20 + 5
