Commutative Property
Associative property
Additive inverse
Identity property
Step-by-step explanation:
In a commutative property multiplication and addition which posses commutative property takes place without considering the order of arrangement of data
12.2 + 18.6 + –4.3 + (–18.6)
12.2 + –4.3 + 18.6 + (–18.6)
The second step results into the presence of a commutative property.
The next step 12.2 + –4.3 + [18.6 + (–18.6)] is an associative property because here, re-grouping of numbers which gives the same result takes place
[18.6 + (–18.6)] is an additive inverse since the result is zero. Additive inverse occurs when the addition of a number to another number results into zero
12.2 + –4.3 + (0) is an Identity property
Identity property occurs when the addition of any number with zero eventually resulted into that number.
