• What does multiplication mean?
• How does 0 times any number equal zero?
• 0 x any number = zero because zero is nothing. For example if you have a problem, 0 x 9 it would be 0+0+0+0+0+0+0+0+0 and that is 0. If it is 9 times 0 that means you have 9 zero times which is 0. So we can draw the conclusion that 0 x any number or any number times 0 = 0.

Hope this helps :)
• Any number divided by 0 is the same number no matter what, right?
• Is anything times 0 = zero?
If we say, "5 x 2", that means we have TWO 5's, so 5 x 2 = 10.
If we say "5 x 1", that means we have ONE 5, so 5 x 1 = 5.
If we say " 5 x 0", that means we have ZERO 5's or no 5's at all! So 5 x 0 = 0
The same rule applies for any other number multiplied by 0.
Hope this helps Dominik!
• how did multiplication originate and was it used the same way?
• I am 9 and i need to learn my 7,8 and 9. Is there any possible trick that i memorize them easily?
• who know what 1,000x1,000 is because idk what it is so please comment if you think or know it because i have no clue what it is so please if you can please help me
• There's a trick to this. You can add zeroes and multiply the other numbers like normal. So 1x1=1 and 3 zeros + 3 zeros = 6 zeros, so 1,000,000, or 1 million
• What does timezing mean
• it means to multiply.:)
