Let's verify on the number line and put = / ≠ in the blank. - 5 + - 3 _____ - 3 + - 5

Given, - 5 + - 3 _____ - 3 + - 5 L . H . S - 5 + - 3 First, we have to locate the first number on the number line which is - 5 Now adding - 3 means we have to move the point, 3 units to the left on the number line. After doing so, we end up at - 8 Now R . H . S - 3 + - 5 First, we have to locate the first number on the number line which is - 3 Adding - 5 means we have to move the point, 5 units to the left. After doing so, we end up at - 8 L . H . S = R . H . S Therefore, - 5 + - 3 = - 3 + - 5

Let's verify on the number line and put = / ≠ in the blank. + 7 + + 2 _____ + 2 + + 7

Given, + 7 + + 2 _____ + 2 + + 7 L . H . S + 7 + + 2 First, we have to locate the first number on the number line which is + 7 Now adding + 2 means we have to move the point, 2 units to the right on the number line. After doing so, we end up at + 9 Now R . H . S + 2 + + 7 First, we have to locate the first number on the number line which is + 2 Adding + 7 means we have to move the point, 7 units to the right. After doing so, we end up at + 9 We get, L . H . S = R . H . S Therefore, + 7 + + 2 = + 2 + + 7

Let's verify on the number line and put = / ≠ in the blank. + 4 - - 3 _____ - 3 - + 4

Given, + 4 - - 3 _____ - 3 - - 4 L . H . S + 4 - - 3 First, we have to locate the first number on the number line which is + 4 Now subtracting - 3 means we have to move the point, 3 to the right on the number line. After doing so, we end up at + 7 Now R . H . S - 3 - + 4 First, we have to locate the first number on the number line which is - 3 Subtracting + 4 means we have to move the point, 4 units to the left. After doing so, we end up at - 7 We get, L . H . S ≠ R . H . S Therefore, + 4 - - 3 ≠ - 3 - + 4

Let's verify on the number line and put = / ≠ in the blank. + 6 - + 7 _____ + 7 - + 6

Given, + 6 - + 7 _____ + 7 - + 6 L . H . S + 6 - + 7 First, we have to locate the first number on the number line which is + 6 Now subtracting + 7 means we have to move the point, 7 to the left on the number line. After doing so, we end up at - 1 Now R . H . S + 7 - + 6 First, we have to locate the first number on the number line which is + 7 Subtracting + 6 means we have to move the point, 6 units to the left. After doing so, we end up at + 1 We get, L . H . S ≠ R . H . S Therefore, + 6 - + 7 ≠ + 7 - + 6

Let's verify on the number line and put = / ≠ in the blank. 0 - - 2 _____ - 2 - 0

Given, 0 - - 2 _____ - 2 - 0 L . H . S 0 - - 2 First, we have to locate the first number on the number line which is 0 Now subtracting - 2 means we have to move the point, 2 units to the right on the number line. After doing so, we end up at + 2 Now R . H . S - 2 - 0 First, we have to locate the first number on the number line which is - 2 . Subtracting 0 means we have to not move the point. After doing so, we end up at - 2 We get, L . H . S ≠ R . H . S Therefore, 0 - - 2 ≠ - 2 - 0

Let's verify on the number line and put = / ≠ in the blank. - 8 - - 5 _____ - 5 - - 8

Given, - 8 - - 5 _____ - 5 - - 8 L . H . S - 8 - - 5 First, we have to locate the first number on the number line which is - 8 Now subtracting - 5 means we have to move the point, 5 units to the right on the number line. After doing so, we end up at - 3 Now R . H . S - 5 - - 8 First, we have to locate the first number on the number line which is - 5 . Subtracting - 8 means we have to move the point, 8 units to the right. After doing so, we end up at + 3 We get, L . H . S ≠ R . H . S Therefore, - 8 - - 5 ≠ - 5 - - 8

Let's verify on the number line and put = / ≠ in the blank. - 13 - + 13 _____ + 13 - - 13

Given, - 13 - + 13 _____ + 13 - - 13 L . H . S - 13 - + 13 First, we have to locate the first number on the number line which is - 13 Now subtracting + 13 means we have to move the point, 13 units to the left on the number line. After doing so, we end up at - 26 . Now R . H . S + 13 - - 13 First, we have to locate the first number on the number line which is + 13 . Subtracting - 13 means we have to move the point, 13 units to the right. After doing so, we end up at + 26 We get, L . H . S ≠ R . H . S Therefore, - 13 - + 13 ≠ + 13 - - 13
