4 + 3 = ?
7

When signs are the same, you add and keep the sign.

+4 +3 = 7

100
-4 + 1
-3

When the signs are different, you subtract
and keep the sign of the larger number.

(+)4 - 1 = 3

Since the 4 was the larger number,
the 3 becomes negative.

100
3 x 5
15

When the signs are the same, you multiply and your answer is positive.

(+)3 x (+)5 = (+)15

100
6 / 3
2

When the signs are the same, you divide and your answer is positive.

100
3 + (-)6
-3
The three is positive and the six is negative.
Signs are different, so subtract and keep the sign of the larger number.
200
-3 - 6 = ?
-9

When signs are the same, you add and keep the sign.

200
8 - 6
2

When the signs are different, you subtract
and keep the sign of the larger number.

(+)8 -6 = 2

Since the 8 was the larger number,
the 2 becomes positive.

200
-2 x -6
12

When the signs are the same, you multiply and your answer in positive.

(-)2 x (-)6 = (+)12

200
-36 / -9
4

When the signs are the same, divide and your answer is positive.

200
-8 - (-1)
-7
This one is tricky because it has a double negative [- (-)1].
Doubles negative = a positive
Therefore, the problem is -8 + 1 = -7

I don't like these either, but you will see them in Algebra.

300
-1 - 3
-4

When signs are the same you add and keep the same sign.

300
-9 + 5
-4

When the signs are different, you subtract
and keep the sign of the larger number.

-9 + 5 = -4

Since the 9 was the larger number,
the 4 becomes negative.

300
3 x -4
-12

When the signs are different, you multiply and your answer is negative.

(+)3 x (-)4 = (-)12

300
-56 / 8
-7

When the signs are different, divide and your answer will be negative.

300
-5 - -2
Double negative again!!!

-5 + 2 = -3

400
1 + 6
7

When signs are the same, you add and keep the sign.

+1 +6 = 7

400
5 - 3
2

When the signs are different, you subtract
and keep the sign of the larger number.

(+)5 - 3 = 2

Since the 5 was the larger number,
the 2 becomes positive.

400
8 x -6
-48

When the signs are different, you multiply and your answer is negative.

(+)8 x (-)6 = (-)48

400
-10 / 5
-2

When your signs are different, divide and make your answer negative.

400
3 + -5 - (-)2
Rewrite it first.
3 - 5 + 2 (Notice how I changed the + -5 to just - 5...same thing)
Read it from left to right.
3 - 5 = -2
-2 + 2 = 0

The answer is 0!

500
-2 - 1 - 7
-10

When signs are the same (no matter how many), you add and keep the sign.

500
-5 + 1 - 3
(-5 + 1) -3 = (-4) - 3 = -7

This is a two part problem. You must use order of operations from left to right.
(-5 + 1) The signs are different, so you subtract and keep the sign of the larger, which = -4
(-4) - 3 The signs are the same, so you add and keep the same sign, which = -7

500
3 x -2 x -4
24

Use order of operations and multiply from left to right.
3 x -2 = -6
-6 x -4 = (+)24

500
-100 / 25 * -2
8

-100 / 25 = -4
Since they had different signs, the 4 was negative.
-4 * -2 = 8
Since they had the same sign, the 8 was positive.

500
-5 - (-)2
-3
Change the double negative to a positive and solve.
-5 + 2 = -3
