Answer:
1. Multiplicative identity:
The number 1; when multiplied by any number, the value of the number does not change.
2. Multiplicative inverse:
The reciprocal of a number; the product of a number and its multiplicative inverse is 1.
3. Commutative property:
a property of the real numbers which states that the order in which numbers are added or multiplied does not change the value
4. Additive identity:
The number 0; when added to any number, the value of the number does not change.
5. Additive inverse:
The opposite or negative of a number; the sum of a number and its additive inverse is 0
6. Associative property:
a property of the real numbers which states that how numbers are grouped in a sum or product does not change the value
7. Distributive property:
a(b + c) = ab + ac, or a(b - c) = ab - ac
Step-by-step explanation:
1. Multiplicative identity:
Ex: 3 × 1 = 3
2. Multiplicative inverse:
Ex: The multiplicative inverse of 2 is 1/2 ⇒ 2 × 1/2 = 1
3. Commutative property:
Ex: 2 + 3 + 5 = 10 , 3 + 2 + 5 = 10 , 5 + 3 + 2 = 10
2 × 3 × 5 = 30 , 3 × 2 × 5 = 30 , 5 × 3 × 2 = 30
4. Additive identity:
Ex: 2 + 0 = 2
5. Additive inverse:
Ex: The additive inverse of 5 is -5 ⇒ 5 + -5 = 0
6. Associative property:
Ex: 2 + (3 + 5) = (2 + 3) + 5
2× (3 × 5) = (2 × 3) × 5
7. Distributive property:
Ex: 2(3 + 5) = 2 × 3 + 2 × 5
2(5 - 3) = 2 × 5 - 2 × 3
