There are three groups of numbers: (1) 1, 2, 3; (2) 0.5, 1.5, 2.5, 3.5; (3) 4, 5, 6. If one number is taken from each group and multiplied, then all of them have There are three groups of numbers: what is the sum of the products of all the three numbers in different ways?

There are three groups of numbers: (1) 1, 2, 3; (2) 0.5, 1.5, 2.5, 3.5; (3) 4, 5, 6. If one number is taken from each group and multiplied, then all of them have There are three groups of numbers: what is the sum of the products of all the three numbers in different ways?

The sum of all products can be obtained by running the combination law
(1+2+3)(0.5+1.5+2.5+3.5)(4+5+6)
This formula is the sum of the products of one number in each group
=6*8*15
=720

If a number is multiplied by any number to get 0, then the number is zero（

If a number is multiplied by any number to get 0, then the number is (0)
I hope I can help you,

Divide 0 by any number to get 0, and multiply 0 by any number to get 0______ (judge right or wrong)

According to the meaning of the question: 0 multiplied by any number will get 0, so, 0 multiplied by any number is equal to 0; 0 can not do divisor, so, 0 divided by any number that is not 0 will get 0, in the original question, "0 divided by any number will get 0" is wrong
