  1. EVERYTHING YOU NEED TO KNOW TO GET A GRADE C ALGEBRA (FOUNDATION) AUTHOR www.mistrymaths.co.uk

  2. a + 2 x b + 3 x c a x b x c 7 + 2 x 3 + 3 x 5 BODMAS says you multiply before you add 7 + 6 + 15 28 Replace the letters with their respective numbers 7 x 3 x 5 105 105 x d = 0 Anything multiplied by zero is zero. So, d must equal zero. 0

  3. BODMAS says you multiply before you add C = 16 + 24 x 10 C = 16 + 240 256 12 months in a year 24 months 2 C = d + 24 x m Solve the equation to work out m 600 = 120 + 24m 20 480 = 24m 20 = m

  4. 5 x 4 20 2 x 4 + 3y = 5 8 + 3y = 5 3y = -3 -1 13 3 x 4 - -1 12 + 1

  5. Replace p with 4 and q with -7 5 x 4 + 2 x -7 20 - 14 6 Replace u with 5 and v with 3 5 x 5 – 3 x 3 25 – 9 16

  6. 5 £5 + 100 x 5p £5 + 500p £5 + £5 10 = £2.50 £7.50 - £5 Cost for calls after £5 a month charge has been taken off Cost for calls after £5 a month charge has been taken off Cost per minute for calls Minutes of calls = 50

  7. Perimeter is the length around a shape + 6y Solve the equation to work out the value of y 56 + 6y = 68 6y = 12 2 y = 2

  8. + 7y Replace p with 4 and q with -7 5 x 4 + 2 x -7 20 - 14 6 Replace u with 5 and v with 3 5 x 5 – 3 x 3 25 – 9 16

  9. 7c - 3y

  10. Remember a minus and a minus is only a plus when you multiply, divide or when the signs are together. When you add or subtract you use a number line. - 3b 12a

  11. 3a + 10 6b 12

  12. + 18 - 4 + 14

  13. + 5

  14. When you multiply powers with the same base you can just add the powers a x a x a x a x a x a When you divide powers with the same base you can just subtract the powers b x b x b x b x b x b x b x b x b b x b x b 1

  15. When you multiply powers with the same base you can just add the powers When you divide powers with the same base you can just subtract the powers y x y x y x y x y x y x y x y y x y x y x y x y

  16. When you multiply powers with the same base you can just add the powers y x y x y x y x y x y x y x y x y When you divide powers with the same base you can just subtract the powers y x y x y x y x y x y x y When you have powers and brackets you can just multiply the powers y x y A negative number to the power of an even number makes a positive Part (iii) As you multiply a decimal by itself more times the number becomes smaller Part (ii)
