Question

Write down the properties of addition and subtraction of integers.​

Answer 1

Step-by-step explanation:

Solution :-

• Properties of addition :-

If a and b are two integer then,

a + b = Sum (Positive sign)

- a + b = Difference (The greater integer sign)

a + (-b) = Difference (The greater integer sign)

-a - b = Sum(Negative sign)

When an integer is added to 0 the sum is the integer itself.

Ex => -3 + 0 = -3

When an integer is added to its reciprocal sign the sum is 0.

Ex => 3 + (-3) = 0

• Properties of subtraction :-

If a and b are two integer then,

a - b = Difference (Positive sign) [When a > b]

a - b = Difference (Negative Sign) [When a < b]

- a - b = Sum (Negative sign)

a - (-b) = Sum (Positive sign)

When an integer is subtracted by 0 the difference is the integer itself

Ex => 3 - 0 = 3
