• If 5 times 9 is 45 is 9 times 5 = 45
• Yes - the product does not change depending on the order in which you multiply.
• Is this just basically times?
• Yes. It is the beginning of multiplication. It is basically just the most simple version.
• why cant you go like 1'2'3'4'5'6'78'
• That is so much slower! if you had to do 12x12, then it would take so long to count all the way up to 144.
• What is skip counting?
• Skip counting is when you count forward or backwards in a times table, for example if i skip count in 3 it would be 3,6,9,12 and so on
• Why is the commutative property called the commutative property?
• Commutative Property is where you can rearrange the numbers and it would still be the same answer. For example, 8+3=11 and 3+8=11. Hope this helps!!
• On the beginning of the video, how do you know there are 3 groups of pigs and 7 in each group? how did you multiply 7x3 which is 21? would you multiply with swaping the numbers? you will get the same amount
• How do you skip count can you make a video on how😅
• 3x144=432 did you know that
• im gona use my cow po pater to see if you two are right
• whats multplokashin like? is it hard?
• Multiplication is basically repeated addition.
If you see 4 x 6, it is 4 groups of 6, so 6 + 6 + 6 + 6 = 24. Many people prefer to memorize their multiplication tables which is memorizing how many groups of what makes what number. But, it is always good to take things easy, especially when you're starting multiplication!
Multiplication is repeated addtion. So it is not very hard, it'll be easy if you work hard!
• What is 1 times 1
• 1 x 1 is 1. anything multiplied by 1 equals the same number.

examples:

2 x 1 = 2
3 x 1 = 3
4 x 1 = 4

even 139792370 x 1 = 139792370
