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?

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

Remainders A simple example: 256 ÷ 3 Type it into the calculator ANSx3= 1. ANS-85= 0.333333333 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.

Square Root and Cube Root 9 + 3 −27 = 0. E.g. 9 + 3 −27 Press

Exponents 3 2 + 7 4 = 2’410. E.g. 3 2 + 7 4 Press

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

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

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
