How do you solve The multiplication property of equality?
The multiplication property of equality is, as the name suggests, a property. It does not require solving!
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 use the commutative property of multiplication to solve a multiplication problem?
You can change the order of the multiplicands to give an intermediate answer that is simpler to work with. For example, to calculate 25 * 45 * 40 you could do 25 * 45 = 1125 and then 1125 * 40 = 45000 Or You could do 25 * 45 * 40 = 25 * 40 * 45 = 1000 * 45 and multiplication by 1000 is simply adding three 0s zero at the end, so 45000. Easy.
How do commutative and associative properties help solve 5x17x2?
5*17*2 The commutative property allows yu to swap the 17 and 2: = 5*2*17 The associative property allows you to group 5 and 2 to evaluate first = (5*2)*17 = 10*17 = 170
How do you solve an equivalent expression using the commutative law?
