  1. + - ± x30 Essential vocabulary for maths ÷ ∞ ≤ () 2

  2. + - ± ÷ ∞ ≤() … You know what they mean – but do you know how to say them? This mini-module presents common ways of saying twenty essential mathematical signs and symbols.

  3. We look at 4 groups of symbols Operators + - x ÷ ± Equalities and inequalities = ≠  ≥ > ≤ < Miscellaneous 0 . ()   Powers If you think you already know how to say them go to slide 32 and check the summary

  4. Operators + - x ÷ ± 3 + 8 three plus eight + a plus sign an addition sign

  5. Operators +- x ÷ ± 7 - 2 seven minus two Alternatives: seven subtract two seven take away two - a minus sign a subtraction sign

  6. Operators + - x ÷ ± 5 x 10 five times ten Alternative: five multiplied by ten x a multiplication sign a times sign

  7. Operators + - x ÷ ± 3 ÷ 8 three divided by eight ÷ a division sign

  8. Operators + - x ÷ ± 3 ± 8 three plus or minus eight ± a plus or minus sign

  9. Question ± So how would you say ?

  10. Question ± So how would you say ? Answer:minus or plus

  11. Equalities and inequalities =≠  ≥ > ≤ < x= 8 x equals eight Alternative: x is equal to 8 = an equality sign an equals sign

  12. Equalities and inequalities =≠  ≥ > ≤ < y ≠ 4x y not equal to four x Alternatives: y is not equal to four x y does not equal four x ≠ an inequality sign

  13. Equalities and inequalities =≠ ≥ > ≤ < y 2.5 y approximately equals 2.5 Alternative: y is approximately equal to four x  an approximate equality sign

  14. Equalities and inequalities =≠ ≥ > ≤ < x ≥0 xgreater than or equal to zero Alternative: x is greater than or equal to zero ≥ an inequality sign a greater than or equal to sign

  15. Equalities and inequalities =≠ ≥ > ≤ < x ≤0 x less than or equal to zero Alternative: x is less than or equal to zero ≤ an inequality sign a less than or equal to sign

  16. Question So how would you say > ?

  17. Question So how would you say > ? Answer: greater than

  18. Question So how would you say > ? Answer: greater than and < ? > and < are strict inequality signs

  19. Question So how would you say > ? Answer: greater than and < ? Answer: less than > and < are strict inequality signs

  20. Miscellaneous 0. ()   0 zero Alternatives: oh nought

  21. Miscellaneous 0 . ()   6.8 six point eight . a decimal point

  22. Miscellaneous 0 . ()  ( ) brackets

  23. Miscellaneous 0 . ()   roottwo the square root of four x plus two y a root sign a square root sign

  24. Miscellaneous 0 . ()    infinity

  25. Powers x squared

  26. Powers x cubed

  27. Powers x to the four Alternatives: x to the fourth x to the power four

  28. Quiz Can you match the words to the symbols? approximately equals less than or equal to plus or minus not equal to greater than divided by equals minus times plus

  29. Quiz Answers divided by greater than equals minus times approximately equals not equal to plus plus or minus less than or equal to

  30. Quiz Can you match the words to the symbols? x to the four x squared point two brackets infinity root two x cubed zero

  31. Quiz Answers point two x cubed zero root two x to the four x squared infinity brackets

  32. Summary

  33. Further reading Of course, there is much more … You can find more useful mathematical vocabulary in your Algebra course book: A2 Core for Edexcel: Page ix ( just before chapter 1)
