you solve the problem in your head with no help from calculators or number lines ect..

please help

it can help you by couting by 2s

You multiply 1.5 X 1.5 and you get 2.25 :] I am glad I could help you, and I hope you do great in future math things xD

i dont know the ansewr im only 5 could yo help me plees

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.

Using the commutative and associative properties of multiplication it is sometimes possible to simply the multiplication.For example, to multiply 35 by 6,35 = 5*76 = 2*3therefore, 35*6 = (5*7)*(2*3) use the associative property= 5*7*2*3 use the commutative property for the middle two terms= 5*2*7*3 use the associative property for the first two terms, and for the other two terms.= (5*2)*(7*3) = 10*21 = 210.

5*2 is 10 and 10*17 is 170

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

the property says that a+b+c is the same as a+c+b and it is the commutative property of addition.

4 = 3 + 1 so 4 + 9 = (3 + 1) + 9 Then, by the associative property, = 3 + (1 + 9) = 3 + 10 = 13

rounding

According to the associative property when more than two numbers are multiplied, the order in which the numbers are multiplied will give the same product.

For example, evaluate 17*5*20: Method 1: (17*5)*20 = 85*20 = 1,700. Method 2: 17*(5*20) = 17*100 = 1,700. Notice that by first multiplying 5*20 to get 100, the calculation is easy to do in your head. You can also use the commutative property to rearrange a question: 5*21*4 = 5*4*21 = 20*21 = 420

Family therapy can help relatives of the mentally retarded develop coping skills.

It is not. You simply multiply length x width.
