What does 2x times 2y mean?
The expression 2x times 2y is an algebraic expression that involves the multiplication of two terms: 2x and 2y. Here, x and y are variables, and 2 is a constant.
To evaluate this expression, we need to follow the order of operations (PEMDAS):
- Multiply 2 and x: 2x = 2 × x
- Multiply 2 and y: 2y = 2 × y
- Multiply the two results: 2x × 2y = (2 × x) × (2 × y)
Simplifying 2x times 2y
Using the distributive property of multiplication over addition, we can simplify the expression 2x times 2y as follows:
2x × 2y = (2 × x) × (2 × y) = 4xy
So, the simplified form of 2x times 2y is 4xy.
