Linear functions are used to model a broad range of real-world problems. The ability to solve linear equations and inequalities is an essential skill for analysing these models. This section covers ...

Simultaneous linear equations are used to model situations where two relationships must be satisfied at the same time. These problems often involve two interdependent variables, such as comparing ...

Use tiles to represent variables and constants, learn how to represent and solve algebra problem. Solve equations, substitute in variable expressions, and expand and factor. Flip tiles, remove zero ...

A solution of this system is a list of values for the \(x_i\)s such that when we substitute them into (2.2), the equation holds. A system of linear equations is consistent if it has a solution, ...

Algebra is part of maths where we use letters to represent unknown values or values that can change. Simplify algebraic terms Algebraic expressions can be simplified by gathering like terms. Like ...

Abstract: STEAM learning is an innovative learning approach because it is considered up-to-date in the industrial era 4.0. capable of supporting 4 (four) basic skills such as critical thinking, ...
