• Why are multiplying and dividing negatives the same?
(64 votes)
• 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?
(14 votes)
• 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!

• Why does the negative cancel out in neg / neg and neg * neg?
(10 votes)
• 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.

• Hey guys. Is a positive+Positive+Negative and Negative or Positive?
(6 votes)
• Depends. if positive + positive is more than the negative it positive ex. 6+4+-5=5 if positive + positive is less than the negative the answer is negative ex. 5+4+-10=-1.

• Why is it hard to remember is the signs will be negative
(0 votes)
• I'm not entirely sure I understand your question, but if you're asking how to remember if an answer to a question will have a negative sign or not, just look at the table at the top of this review again. As a refresher:
positive x positive = always positive
negative x negative = always positive
positive x negative = always negative
negative x positive = always positive
And the same is always true when you're dividing too. Hope this helps.
