subract 6 from -7. This is basic math and I need help. How do you do this?

Question

I am taking a math assessment test at 1pm today and I need some help jogging my memory so I don't have to take remedial math. Can you help me?

Answer 1

I learnt this in secondary school and I still use it.

Guy stands on a number line

'-7'

Standing on -7

'Subtract'

He faces towards the negative end of the scale

'6'

He walks 6 numbers towards negative infinity

He stops on -13


Hope that method works for you

Answer 2

-7-6= -13

using a number line you can see that if you are at position - 7 and you move minus 6 I.e 6 steps to the left you end up at position -13

-14 -13 -12 -11 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10

Answer 3

just think of it this way....
you have -7 which you can think of it visually on a number line like:
-10, -9, -8, *-7*, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
because you already have a negative number and you are wanting to essentially "take away 6" you will move 6 spots down the line on the left (negative side) since you are subtracting... this means that since you continue down 6 spots, you now arrive at -13

therefore -7-6=-13

Answer 4

Subtract a negative number from a positive number is the same as adding it:
12 - (-2) = 12 + 2 = 14

Subtract a positive number from a negative number is the same as subtracting it.
(-12) - 2 = -(12+2) = (-14)

Subtract a negative number from a negative number is the same as adding the negative difference of each answer:
(-12) - (-2) = -(12-2) = (-10)
UNLESS the second number is smaller than the first:
(-12) - (-14) = -(12-14) = -(-2) = 2

Adding a positive and negative number is the same as the positive minus the negative number:
3 + (-6) = 3 - 6 = (-3)
6 + (-3) = 6 - 3 = 3

Adding two negative numbers is the same as negative sum of them:
(-12) + (-7) = -(12+7) = -(19)

Multiplying two negative numbers is the same as the positive product of them:
(-3)*(-5) = 3*5 = 15

Multiplying a negative and a positive number is the same as the negative product of them:
(-3)*5 = -(3*5) = -(15)

Dividing a positive number from a negative is the same as the negative division of them:
(-12)/4 = -(12/4) = (-3)

Dividing a negative number from a positive is the same as the negative division of them:
8/(-4) = -(8/4) = (-2)

Dividing a negative number from a negative number is the same as the positive division of them:
(-24)/(-8) = 24/8 = 3

I hope this helps :)

Answer 5

-7 -6 = -13

Answer 6

-7-6 = -13

Answer 7

To make it easier, you could change all the negatives to positives, then flip it back at the end. In other words...

Take the original problem:
   ( -7 ) - 6 = ?
Change it to positives:
   ( +7 ) + 6 = ?
   7 + 6 = ?
Solve the problem:
   7 + 6 = 13
Change it back to negatives:
   -7 - 6 = -13

Answer 8

-13

think of it as -7 -6 which is like -(7+6) i.e. whatever 7+6 is but negative. 6+7 is 13, so it's -13

but if you need help with this sort of thing, maybe remedial math isn't such a bad idea?

Answer 9

imagine a line with marks going across it for each number. in the middle is 0 (zero) and to the right is positive numbers, to the left negative. Start at -7 and subtract 6 more lines. you will be at -13.

Answer 10

-7 -[6 ]convert -7+-6=-13
