What property is x plus 3 equals x plus 3?
Addition is the same no matter what order it is in. If x is 2, then 2+3=5 and 3+2=5 are the same. They are all in the same fact family. Multiplication is the same no matter what order it is in as well. x times 3 is the same as 3 times x If x is 2, then 2*3=6 and 3*2=6 Fact families!
How can you use addition to find the variable in subtracting equations?
x-3=0 so add 3 to both sides to isolate the variable. x-3=0 +3 | +3 ________ x-3+3=o+3 _________ x=3
What is the property of -3 plus 6 equals 6 plus -3?
The property you described, where x + y = y + x, is called commutativity. In the case of addition, it is called the commutative property of addition.

How can you use addition to find the variable in subtracting equations?
x-3=0 so add 3 to both sides to isolate the variable. x-3=0 +3 | +3 ________ x-3+3=o+3 _________ x=3
What is the property of -3 plus 6 equals 6 plus -3?
The property you described, where x + y = y + x, is called commutativity. In the case of addition, it is called the commutative property of addition.
How do you write math expression for the product of 3 and the sum of x and 12?
3(x+12), where the parentheses state that you must do the addition first.

the fact family of the numbers 3, 6, and 18 is: 3 x 6 = 18; 6 x 3 = 18; 18 ÷ 3 = 6; 18 ÷ 6 = 3
How does knowing an addition fact help with a subtraction fact?
You can do the fact backwards. ex. 3+4=7 turn it around 7-4=3 I believe it is called doing the inverse operation.
