8. Calculating Time Press If Suzy gets onto the bus at 10:22 am and gets off the bus at 1:51pm, how long was she on the bus for?

9. Don’t worry, we got this First convert times to 24 hour time: 10:22 stays the same 1:51 becomes 13:51. Now type in 13º51-10º22_ 13º51-10º22= 3º29’0.”

10. Remainders A simple example: 256 ÷ 3 Type it into the calculator To find the remainder subtract the answer ( ) And multiply by the divisor ( ) And the final answer is your remainder. ANS-85= 0.333333333 ANSx3= 1.

12. Exponents

13. PRIME FACTORIZATION!!!!!! Press Type in the number you want to prime factorize. Press Tada!! 96 = 2 5 x3

14. Lowest Common Multiple and Highest Common Factor E.g. Find the LCM and HCF of 180 and 96 Write all the factors of 96 down in a row: 2 x 2 x 2 x 2 x 2 x 3 Find the prime factors 180 And match them with the factors of 96, if they don’t match, start a new column 180= 2 2 x3 2 x5

15. Like this: 96=222223 180=22335 Columns that match are for the HCF and all the columns multiplied will be the LCM: HCF = 2 x 2 x 3 = 12 LCM = 2 x 2 x 2 x 2 x 2 x 3 x 3 x 5 = 1 440

16. Percentages Adding 14%: 14% of 256: Try. to change the way answer looks

17. Class marks Press Type in what you are converting to, e.g. 100 Press Type in what you are converting from, e.g. 80 Press Type in first student’s mark Press Then simply type in the next student’s mark and again

18. Pythagoras Type in the x-coordinate Press Then type in the y-coordinate Press

19. Multiples Lets find the multiples of 16: Press 16 X_ X ANS 0 0 1 16 2 32 0.

20. Patterns E.g. 3x +1 Press 3X+1_ X ANS 0 1 1 4 2 7 0.

21. Factor Pairs Finding Factor pairs of 36 Type in X ANS 0 -------- 1 36 2 18 0.
