help with the following math?

Question

multiply -3*[-8]
subtract -4-[-16]
subtract -8-7
add 8+[-20]
divide -63 by 7 and 32 by -4

Answer 1

hold on
-3*-8= 24
-4-[-16= -20
-8-7=-15
8+-20=-12
-63/7=-9
32/-4=-8
hope it helps!

Answer 2

Well, I would like you to understand the principles of each equation, so I'll see if I can explain them to you as well as give you the answers.

1.) Multiply: A negative x a negative =positive, so -3 x -8=24.

2.) Subtract: When 2 negative signs are used together (i.e. when you subtract a negative), the signs negate to positive, so
-4--16 is basically just -4+16, which would be 12.

3.) Subtract: When you subtract a negative by a positive, is is the same as adding to negative numbers, so -8-7 would be -8 + -7, which would come out to be -15.

4.) Not much to explain here, it's just -12.

5.) Divide: When you divide a negative by a positive or a positive by a negative, the quotient always stays negative. So -63/7 = - 9
and 32/-4 =-8.

Answer 3

You are getting some wrong answers from other people.


(-3)(-8) = +24 (neg x neg is pos)

-4-(-16) = -4 + 16 = 12

-8 - 7 = -15 (a loss of 8 and a loss of 7 is a loss of 15)

8 + (-20) = -12 (a gain of 8 and a loss of 20 is a loss of 12)

-63/7 = -9 (neg divided by a pos is neg)

32/-4 = -8 (pos divided by a neg is neg)

Answer 4

-3*[-8] = 24

-4-[-16] = -4+16 = 12

-8-7 = -8+[-7] = -15

8+[-20] = 8-20 = -12

-63/7 = -9 and 32/-4 = -8

Answer 5

this is a trick question no longer with the aid of content cloth, yet with the aid of assumed answer. there is not any lacking greenback. The area that anybody messes up on is the equation. this is right that $9 x 3= $27 and that the bell boy has $2, yet you won't be in a position of upload ($27 + $2) at the same time. Why? with the aid of fact, If the bell boy is given $5 lower back, and he wallet $2, then there is only $3 left. The bell boy then divides that $3 into 3 (for all the adult adult males). which ability each and each guy gets $a million, no longer $3, which equals $3 funds lower back in entire. So, the quantity lacking is $2, which the bell boy already has. Plus, the fee of the inn is now no longer $30 yet $25. for that reason, the breakdown is as follows: the fee of the inn is $25 ($30-$5). The bell boy has $2. each and all the adult adult males have $a million = $3 in entire. 25 + 2 + a million+ a million + a million = 30. no longer something lacking, nevertheless $30.

Answer 6

ok
-3(-8)=24
-4-(-16)= -12
-8-7= -15
8+(-20)= -12
-63 divided by 7 = -9
32 divided by -4 = -8
easy math learned it last year

Answer 7

-3*(-8)= +24
-4-(-16)=+12
-8-7= -15
8+(-20)=-12
-63 by 7 = -9 & 32 by -4 = -8

Answer 8

no problem
-3*(-8) = 24
-4-(-16) = 12
-8-7 = -15
8+(-20)= -12
-63/7 = -9
32/-4 = -8

Answer 9

-3*[-8] = 24
-4-[-16] = 12
-8-7 = -15
8+[-20] = -12
-63/7 = -9
32/-4 = -8

Answer 10

Hints:

Multiplying two negative numbers make a positive number -4 * -3= +12

A negative in front of a negative makes is positive. -2-(-4) becomes -2 + 4 = +2

Subtracting two negative numbers will give a negative answer. -3-4= -7

Example: 4+ [-40]= -36

Hint: With division, one negative number will make the answer a negative number.

I hope this helps.
