Patterns and Algebra Review

Please study the following:

- patterns and then writing down the rules.

for example:  3, 7, _____, 15, 19 (the missing number is 7 and the rule is +4)

we will ask harder questions such as subtraction patterns such as:

65, 58, _____, 44  (the missing number is 51 and the rule is -7)

we will ask multiplication questions such as:

9, 27, ______, 243 (the missing number is 81 and the rule is x 3)

we will ask division questions such as:

200, 100, _____, 25 (the missing number is 50 and the rule is divided by 2)

we will ask decimals questions such as:

3.4, 3.8, 4.2, _____, (the missing number is 4.6 and the rule is that it is going up by 0.4)

for example:

find y:

14 + y = 65
y = 51

Remember that + is opposite to -

multiplication is opposite to division

For Mr Lima's group, remember the vortex.

You must also remember mathematical language:

For example:

Increase means to add
sum means to add
difference means subtraction
double means to multiply a number by 2
is means = (equals)

- We will also ask questions related to tables like the one below.

Questions related to BODMAS.

Watch the video https://www.youtube.com/watch?v=dAgfnK528RA&t=85s which explaisn about BODMAS.
