What are equivalent expressions

The video tutorial explains equivalent expressions, which are expressions that have the same value even if they look different. It introduces the concept using the equal sign and provides examples like 7 = 7 and 3 * 4 = 4 * 3, illustrating the commutative property. The tutorial also covers properties such as a + 0 = a, emphasizing that expressions can be equivalent even if they appear different. Finally, it discusses equations, using examples to show how expressions on both sides of an equation are equal.

What does it mean for two expressions to be equivalent?

• They look exactly the same.

• They have different values.

• They are always numeric.

• They have the same value.
