Welcome to our Year 7 lesson on Algebraic Notation: Multiplying Terms! In this video, we'll explore how to simplify algebraic expressions by multiplying terms and applying key algebraic rules.
Learning Outcome:
By the end of this video, you will be able to:
Simplify algebraic expressions involving multiplication.
Key Concepts:
In algebra, the multiplication sign is usually omitted.
Numbers are placed in front of letters when multiplying terms.
Examples:
3 x a becomes 3a
a x b becomes ab
p x q x r becomes pqr
2a x 4b simplifies to 8ab
a x a becomes a² (a squared)
a x a x a becomes a³ (a cubed)
Practice Questions:
Simplify the following using algebraic notation (watch the video for more detailed examples).
Challenge Questions:
Write down the expression for the area of a rectangle where the x-axis is 6ab, and the y-axis is 4b.
Write down the expression for the area of a triangle where the x-axis is 4a², and the y-axis is 5a.
Answer Key:
Area = 24ab²
Area = 10a³
