Question

Using the number line, write the integer which is

(a) 4 more than -5.

(b) 3 less than 2.

(c) 2 less than -2.

Answer 1

(a)

• Firstly, we draw a number line.
• Find the point -5 on the number line.
• Move 4 units to the right of -5 on the number line.

On moving 4 units to the right of -5 on the number line we reach at -1.

Hence, 4 more than -5 is -1.

(b)

• Firstly, we draw a number line.
• Find the point 2 on the number line.
• Move 3 units to the left of 2 on the number line.

On moving 3 units to the left of 2 on the number line we reach at -1.

Hence, 3 less than 2 is -1.

(c)

• Firstly, we draw a number line.
• Find the point -2 on the number line.
• Move 2 units to the left of -2 on the number line.

On moving 2 units to the left of -2 on the number line we reach at -2.

Hence, 2 less than -2 is -4.
