• 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.
• 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
• 7 times 5 =35
• Yes or 35=7x5
• what do i do wen done
• Well, you finished then. Do some more Khan Acadamy or if you have free time do something you enjoy doing!
