Q. Example

2

: Fill in the blanks with suitable numbers to make the statements correct.

\newline

(i)

7 \times(-2+3)=7 \times(-2)+7 \times 3

\newline

(ii)

3 \times(-4+2)=3 \times 2+3 \times 2

\newline

Solutions:

Apply Distributive Property: For (i) use the distributive property of multiplication over addition: $7\times(-2+3)$ should equal $7\times(-2)+7\times3$ . Calculate each side to check if they are equal.
Use Distributive Property Again: For (ii) use the distributive property again: $3\times(-4+2)$ should equal $3\times(-4)+3\times2$ . Calculate each side to check if they are equal.
