## Want to join the conversation?

• so its like if its 80 divides by 10 its going to be a single digit from 80 so 8?
• Yes, move the dot to the left as many zero you have.
80=80.0
80.0 / 10 = 8.00
435.45 / 100 = 4.3545
0.23 / 10 = 0.023

etc
• will there be a divide sign on a keyboard soon
• there is all ready is its the / I think
• i need help with math the ones that have a number then this =
• so say have 10 divided by 2 that would = 5 since 5x2=10.
Another example is if you have 100 divided by 10 that would equal 10 since 10 x 10= 100. Get it now
• will there ever be a dividing symbol on a keyboard?
• you can just use / it means the same thing
• Why are the videos Lindsey do so long?
• I don't know
• this doesn't make any sense to me can anyone explane?
• when you are dividing by 10 like 650 divided by 10 you simply take away the 0 at the end of the first number and thats the answer so with 650 divided by 10 the answer is 65. I hope that helped
• I don’t understand 10x990,000! I’m having a meltdown!
• To multiply any whole number by 10, attach a 0 on the right. So 10x990,000 = 9,900,000.

Have a blessed, wonderful day!
