How can associative property of multiplication can help solve math problems mentally?
You can do the easy bits first. Thus, to calculate 7*5*2, instead of doing 35*2 = 70, you can calculate 7*10 = 70. By itself, the associative property is not as useful as it is in combination with the commutative and distributive properties.
How do you solve an equivalent expression using the commutative law?
4+m
Can the distributive property be used to solve 4 times 30?
Yes, but it would be a pointless thing to do. The associative property is much more appropriate.
How do you solve associative in equation?
The associative property means that in a sum (for example), (1 + 2) + 3 = 1 + (2 + 3). In other words, you can add on the left first, or on the right first, and get the same result. Similar for multiplication. How you use this in an equation depends on the equation.
How do you solve sums based on commutative property of multiplication?
The commutative property of multiplication states that changing the order of numbers does not change the result or it's value. For example: If 3+2=5 Then 2+3=5 In multiplication: If 3x2=6 Then 2x3=6 There for 3x2=2x3
