• Rearranging equations d m v =
• balancing c = b + a
• balancing c + 50 = b + a + 50
• balancing c a + b 2 2 =
• balancing c + 50 = b + a + 50 c = b + a c a + b 2 2 =
• Get the subject on the left c = b + a b + a = c
• Order not important for addition a + b = b + a 2 + 3 = 3 + 2
• Order not important for multiplication ab = ba 2 x 3 = 3 x 2
• Remember: a x b c a x c b a b c x
• Remember: 2 x 3 4 2 x 4 3 2 3 4 x
• Hint 1 a + b = c
• Hint 1 a + b – b = c - b
• Hint 1 a = c - b
• To undo an operation Do the opposite
