Question

Using the number line write the integer which is: 6 less than 2

Answer 1

Hint: Here, draw a number line containing 0 and left side contains negative numbers and right side contains positive numbers. Now, 6 less than 2 means we have to move 6 six steps towards the left starting from 2. Where we reach is the result.

Complete step-by-step answer:
For this draw number line as below. Now, for 6 less than 2, move six steps towards the left of the number 2, we reach the number – 4, so – 4 is the result.
In these types of questions, draw a number line and mention both positive and negative numbers on both sides of 0, 0 is the midpoint of the number line. If we subtract a number from a particular number, then we have to move towards left from that number and the number of steps moved will be same as the number subtracted, similarly, if we add a number from a particular number, then we have to move towards right from that number and the number of steps moved will be same as the number added. Also, multiplication and division can be performed using this method.

So, the correct answer is “-4”.

Note: This is the geometrical method of calculations, but we can use this method for small numbers, because we cannot draw very large number lines which can contain numbers like 100, 1000 etc. This method also has restrictions with irrational numbers and fractional numbers, because it is not easy to mention irrational numbers on a number line. Algebraic methods can be used for operations of large numbers.
Alternatively, 2 – 6 = − 4
