1 Year 7A Mathematics Homework Autumn Term Week Name : 4 5 Teacher: Class: Target: The blank sheets should be used for working out

2 Negative Numbers Top tip: Use these to help you! Equations Top tip: Tips and hints- Autumn 1 Products of prime Top tip: Draw a prime factor tree 2 x 7 = 14-2 x 7 = x -7 = x -7 = = = = = 3 Long Multiplication Top tip: Use an appropriate method e.g. Grid method 342 x e.g. 5x + 4 = 2x + 13 Take smaller amount of x from each side 3x + 4 = 13 Use inverse operations 3x = 9 x = 9 3 x = 3 Expanding brackets Top tip: Multiply every term inside the bracket by the number outside the bracket e.g. Expand 3m(5m 7) = (3m x 5m) (3m x 7) Add all underlined values = 4788 = 15m 2 21m
