Hi!

Here is the explanation for the distributive property of integers.

?

Let?x,?y,?and?z?are any three integers, then?distributive property?of integers can be stated as

x?? (y?+?z) = (x???y) + (x???z).

x?? (y???z) = (x???y) ? (x???z).

?

x?? (y?+?z) means that first of all we need to add?y?and?z, then this result is multiplied with?x.

x?? (y???z) means that first of all we need to subtract?z?from?y, then this result is multiplied with?x.

?

Let us take?x?= 5,?y?= 19 and?z?= ?27

According to?distributive property?of integers the value of the expression 5 ? [19 + (?27)] must be equal to the expression 5 ? 19 + 5 ? (?27) and the value of the expression 5 ? [19 ? (?27)] must be equal to the value of the expression 5 ? 19 ? 5 ? (?27).

?

You can verify these

Now, 5 ? [19 + (?27)] = 5 ? (?8) = ?40

5 ? 19 = 95 and 5 ? (?27) = ?135

??5 ? 19 + 5 ? (?27) = 95 ? 135 = ?40

Thus, 5 ? [19 + (?27)] = 5 ? 19 + 5 ? (?27)

?

Similarly, you can verify 5 ? 19 + 5 ? (?27) = 5 ? [19 ? (?27)] = 5 ? 19 ? 5 ? (?27)

?

Not only that you can verify this property by considering three arbitrary integers?x,?y?and?z

?

Hope! You got the concept of distributive property of integers.

?

Cheers!

Question 1.

Find the value of the following using the number line activity.

(i) (-4) + (+3)

(ii) (-4) + (-3)

(iii) (+4) + (-3)

Solution:

(i) (-4) + (+3)

To find the sum of (-4) and (+3), we start at zero facing positive direction continuing in the same direction and move 4 units backward to represent (-4).

Since the operation is addition we maintain the same direction and move three units forward to represent (+3)

We land at -1

So (-4) + (+3) = -1
