  1. The Wonderful World of Algebra Part one: Writing Equations

  2. Learning Objectives • To be able to write and construct equations • To begin to understand how to Collect Terms

  8. y g y g b b r r r r Look at this diagram: Which of these equations are true and which are false?... • b = g + y • g = 2r • b – g = y • 2y + 2g = 4r • 2(y + g) = b + 2r

  9. y g y b b b y r r r g Look at this diagram: Which of these equations are true and which are false?... • g + 2y = 3r • g + r – y = b • 3r + g – 2b = y • b – g = y • 3r + g – 2b = b - g

  10. b b b r b g g y y y y y y y y y y y y r r r r r r Write down some equations from this diagram:
