Daughter's homework,,,how do you multiply or divide with positive & negatives - example (+6) x (-3)?
Answers:
=-18.anytime you multiply or devide with negative your answers will always be negative
answer = -18
We're not here to do people's homework
a positive times a negative equals a negative. A negative times a negative is a positive. And the answer is -18.
+ x - = -
- x - = +
tell her to ask her teacher thats what they get paid to do.

a negative times a negitive is a positive.
a positive times a positive is of course a positive
a positive times a negative is a negative
a negative times a positive is a negative
a negative times a negative is a positive
other than that all the general rules for multiplication remain unchanged,
Do you have a spreadsheet program on your computer?
If so bring it up and type the following into one cell.
=sum((+6)*(-3))
Your result will be -18.
First, you multiply or divide the numbers together as if they were normal, and then add the negative sign, if necessary.
*Hint: If there is an odd number of negative signs, (i.e. -2 x 4 x -3 x -1) then the answer will be negative, but if there is an even number of negative signs (-2 x 5 x -3) then the answer will be positive.
a psoitive times a negative is a negative. plus we cant forget 6 times 3 which equals 18. so yoour answer is: -18.
if you don't know tell her she needs to talk to her math teacher
The problem is that a lot of people have probably used their calculator to help you.
Like many people have already posted: - x - = +, + x +=+ and + x - or - x + = -
the solution is this!
(+6) * (-3) = (+1) * 6 * (-1) * 3 = (+1) * (-1) * 6 * 3 =-18
Therefore!
(-1) * 18 =-18
first ignore the signs
6*3=18
if the signs are different the answer is negative
if the signs are the same the answer is positive
so, in this case the answer is -18
A positive times a negative is a negative, so the answer is -18. Other information about multiplying with positives and negatives: A negative times a negative is a positive, and a positive times a positive is a positive.
Minus x minus = plus
minus x plus = minus
Didn't you go to school, you dolt?
(+6) x (-3) = -18
(-6) x (+3) = -18
(-6) x (-3) = 18
6 x 3 = 18
If they are both of the same sign, the answer will be positive.
If they are of different signs, the answer will be negative.
Further examples,
(-2) x (-3) x (-4) = (+6) x (-4) = -24
(-2) x (-3) x (+4) = (+6) x (+4) = 24
(-2) x (+3) x (+4) = (-6) x (+4) = -24
I hope that you can understand this better now.
For every multiply or divide questions
the combination of:
+ & + , the answer will end up + . (e.g 6 x 6 =36)
+ & - or - & +, the answer will end up - . (e.g -2 x 3 = -6)
- & - , the answer will end up + . (e.g -8 x -12 = 96)
positive times positive = positive, negative times negative = positive, positive times negative= negative.it's that easy - bit like magnets.
A negative multiplied by a negative is positive.
A negative multiplied by a positive is negative.
A positive multiplied by a positive is positive.
A negative divided by a negative is positive.
A negative divided by a positive is negative.
A positive divided by a negative is also negative.
A positive divided by a positive is positive.
This is where the saying two wrongs make a right really comes into action. Two negatives, multiplied together or divided by each other, make a positive.
And the answer to 6 x -3 = -18.
= -18
Count the number of negative numbers in your sum. If there is an even number, then the answer will be positive; if an odd number, then the answer will be negative.
So, for example: 3 x -2 x -5 = ?
There are two negative numbers (even), so the answer is positive. Then, just do the maths on the numbers (i.e. 3x2x5 = 30). So the answer is + 30.
Another example: (3 x -4)/6 = ?
There is only one negative number (odd), so the answer is negative. Then do the maths (i.e. 3x4/6 = 12/6 = 2). so, the answer is -2.
If the signs are the SAME the answer is POSITIVE
If the signs are DIFFERENT the answer is NEGATIVE
first of all multiply the numbers
so 6 x 3 = 18
Next do the - and +
minus + plus = minus
minus + minus = plus
plus +plus = plus.
the answer is -18
Let me know if it helps or not!
6x3 except the value of the larger
First forget about positive or negative sign and just multiply as if you were multiplying positive numbers. Then remeber that,
+ x + = +
+ x - = -
- X - = +
Now put the sign appropriately
It is the same for division
+/+ = +
+/ - = +
-/+ = -
-/- =+
The answer 4that 1 is -18
When u multiply or divide integers take note of this: same sign=positive, different signs=negative
same sign gives +
different signs gives -
e.g -4 x -8 = 32
-x- = +
+x+ = +
-x+ = -
+x- = -
it also works for division as the same signs just cancel out
