Understanding Expressions and Equalities
In mathematics, when two numbers undergo addition, subtraction, multiplication, or division, the result is always another number.
Now, consider the case where a mathematical operation on two numbers yields the result 12. Possible number pairs that satisfy this condition include:
- (6 + 6)
- (15 − 3)
- (6 × 2)
- (24 ÷ 2)
Each of these represents a mathematical expression, where the value of each expression is 12. These expressions can be written as:
(6 + 6) = (15 − 3) = (6 × 2) = (24 ÷ 2)
Such an arrangement, where two expressions hold the same value, is referred to as equality.
For example:
- (6 + 6) = (15 − 3)
- (6 + 6) = (24 ÷ 2)
- (6 × 2) = (15 − 3)
