Question

commutative law at the addition and multiplication integers x=40,y=30=​

Answer 1

• Commutative Law under addition:

If x , y are two integers, then

$\boxed { \pink { x + y = y + x }}$

$Here, x = 40 , y = 30;\\40 + 30 = 30 + 40 = 70$

• Commutative Law under multiplication:

If x , y are two integers, then

$\boxed { \pink { x \times y = y \times x }}$

$Here, x = 40 , y = 30;\\40 \times 30 = 30 \times 40 = 1200$
