Grade 9 de-streamed — Simplify algebraic expressions by applying properties of operations of numbers, using various representations and tools.
Grade 9 de-streamed — Simplify algebraic expressions by applying properties of operations of numbers, using various representations and tools, in different contexts.
A note on this mapping: MTH1W simplifies expressions by collecting like terms and multiplying monomials; multiplying two binomials and the special products are Grade 10 (MPM2D), so the tag covers the first half of this skill.
The 2 skills that cover it
- Variables & ExpressionsUse letters to stand for unknown or changing quantities, evaluate expressions, and combine like terms.Read the lesson →
- PolynomialsName a polynomial by its degree and number of terms, add and subtract polynomials, multiply a monomial or a binomial through, and recognise the special products.Read the lesson →
