Answer 1

Number line:

• In essence, a number line is a straight line, but its length is divided into the necessary number of equal segments, each segment being represented by a real number. The arrow heads at both sides of the number line show that the line and real numbers can be stretched up to infinity at both sides. By comparison, it is primarily used to pinpoint the location of any point on the aircraft. It is also employed to comprehend mathematical operations.
• Any length straight line should be drawn, Divide the length of the straight line into the necessary number of equal segments by marking points. Identify the centre point and represent it as zero. Represent the points on the right and left sides of the centre as positive and negative real numbers, respectively.

Here, we have drawn a number line marking the account balance of the three children on the line.
