# Level 3-4 Algebra - Getting Started

Algebra is a big deal in KS3 Maths. But what's the fuss about? Well, in algebra, we swap numbers for letters. Why? To represent numbers we don't know yet.

This quiz is like a launchpad into cool things! Algebra buddies up with BIDMAS (or BODMAS – same thing) and unlocks doors not just in maths, but also in science, geography, engineering, and even medicine. The last 300 years of tech magic? Yep, algebra played a role. Plus, you can sprinkle algebra magic in your everyday life!

1.
Sam has x guinea pigs, Paul has y guinea pigs and Joseph has z guinea pigs. We know that Sam and Paul together have the same number of guinea pigs as Joseph. How would we write this?
x + y = z
xyz
2x + y
x - y = z
Sam's (x) + Paul's (y) = Joseph's (x)
2.
Peter has x oranges and Joe has three more oranges than Peter. How would we write the number of oranges that Joe has?
3x
x + 3
x + x + x + x
x3
3 more is the same as + 3

5.
Which of these is not an 'equation'?
3x = 7
4x2 - 6 = 28
4x + 5y + 6z

An 'equation' always contains an = sign
6.
Thomas has x marbles and Richard has only one third as many. How would we write the number of marbles that Richard has?
