• Why are multiplying and dividing negatives the same?
• Multiplying and dividing negatives are the same because there is no difference between those sides of zero except the side of zero. So, when you multiply or divide negatives, you are basically multiplying positives with minus signs behind them. Don't forget that the product of 2 negative numbers is always a positive.

• why do people use . ( dot symbol) instead of x. if x is used common in algebra why did they put x in multiplication?
• X is a simpler way of teaching kids. Little kids might think they’re smarter than they really are and think that it’s a decimal point. As you get older, you realize the difference between this sign and a decimal point. Hope this helped!

• yay, math, definately fun.
• no math is not fun at all! Math = horrible
• Why does the negative cancel out in neg / neg and neg * neg?
• Because you are adding to it's self making a positive, with integers you always do the inverse operation well let me not say always for certain operations.
