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 
13º51-10º22_
13º51-10º22=
3º29’0.”
First convert times to 24 hour time:
10:22 stays the same
1:51 becomes 13:51.
Now type in

10. Remainders A simple example: 256 ÷ 3 Type it into the calculator
ANSx3= 1.
ANS-85=
256÷3=
85 1 3
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.

13. PRIME FACTORIZATION!!!!!! Press
96 =
25x3
Press
Type in the number you want to prime factorize.
Tada!! 

14. Lowest Common Multiple and Highest Common Factor
180=
22x32x5
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

15. Like this:
96= 2 3
180= 5
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
