Question

find 4+5;6+3+5 and1+6 using the number line​

Answer 1

(1)We will begin at zero and move 4 units to the right to reach the first integer of addition representing 4.

(2)Since the second number is positive, move 5 units to the right.

(3)Here we will arrive at added number i.e. 9.

B=2+6B=2+6

(1)We will begin at zero and move 2 units to the right to reach the first integer of addition.

(2)Since the second number is positive, move 6 units to the right.

(3)Here we will arrive at added number i.e. 8.

C= 3 + 5C= 3 + 5

(1)We will begin at zero and move 3 units to the right to reach the first integer of addition.

(2)Since the second number is positive, move 5 units to the right.

(3)Here we will arrive at added number i.e. 8.

D= 1 + 6D= 1 + 6

(1)We will begin at zero and move 1 unit ahead to the right to reach the first integer of addition.

(2)Since the second number is positive, move 6 units to the right.

(3)Here we will arrive at added number i.e. 7.

Note- We must know the rules to add integers like when the two integers have the positive sign, add them and put the (+) sign to the sum. Also we must start from the first integer of addition and then take additional units of second integer to get the right answer.
