A litre does not measure mass or weight but volume, i.e. what an object occupies.

It's volume!

Let's start off easy – a litre is a unit of what?

"The power of" designates how many times a number is being multiplied by itself, and is also known as an exponent or indices. Basically, 5 x 5 = 25, and 5 x 5 x 5 = 125, and 5 x 5 x 5 x 5 = 625.

What is the value of 5 to the power of 4?

When you multiply a number by another number, you get a multiple of the original number. So beginning with 1 – 12 x 1 = 12, 12 x 2 = 24, 12 x 3 = 36, and so on. For every number, there are an infinite number of multiples.

12, 24, 36

What are the first three multiples of 12?  


We know there is one bull for every twenty cows, so to find out how many bulls there are for 160 cows, you divide 160 by 20 to get 8 bulls.

It's 8!

On a farm, the number of bulls : the number of cows = 1 : 20. If there are 160 cows, how many bulls are on the farm?  


The mean (or average) of a group of numbers is calculated by adding them all together and dividing the total by how many numbers there are, so 9 + 14 + 7 + 17 + 8 = 55, and 55 ÷ 5 = 11!

It's 11!

Calculate the mean of these five numbers:  
9, 14, 7, 17, 8  


Pardon my terrible drawing, but congruent shapes have the same size and shape – their sides, segments, and angles are all identical. In D, the main shape has just been rotated 90º to the right.

It's D!

Which of the shapes below is congruent to this shape?

Because 5x and 9x are the same letter, you can simply combine them to get 14x. Therefore, the new simplified equation is 14x – 2.

14x – 2

Simplify this equation:  
5x – 2 + 9x  


MM stands for 2000, X is 10, and IX is 9!

2019

Which year is written in Roman numerals as MMXIX?

Factors are numbers which divide exactly into another number with no remainder. For instance, the factors of 4 are 1, 2, and 4. The highest common factor of two numbers is the largest integer that divides into both of them exactly. In this case, that number is 6.

Determine the highest common factor of 66 and 30:

A cube number is a number that has been multiplied by itself 3 times; therefore, 10 x 10 x 10 = 1,000.

1,000

As you can see, when you locate the middle of line AB and trace its location on the grid, you find it lines up with 3 on the x axis and 3.5 on the y axis. Coordinates are always written as the value of x axis followed by the value of the y axis.

(3, 3.5)

Line AB is shown on the grid below. A is the point (0, 2) and B is the point (6, 5). What are the coordinates for the midpoint of line AB?

Only a reflex angle is bigger than 180º – an acute angle is less than 90º, a right angle is exactly 90º, and an obtuse angle is between 90º and 180º.

It's a reflex angle!

What kind of angle is bigger than 180 degrees?

A linear sequence increases (or decreases) by the same amount each time, in this case by 3. This makes 3 the "common difference" in the sequence, therefore it relates to the 3 times table. But the sequence doesn't begin with 3, it begins with 8. So we write +5 to signify that sequence is 5 integers ahead of every corresponding term in the 3 times table.

3n + 5

Here are the first four terms of a linear sequence: 8, 11, 14, 17.  
What is the nth term?  


When converted into fractions over 1000, 9/25 is 360; 0.371 is 371; 38% is 380; and 2/5 is 400/100, making it the largest,

9/25, 0.371, 38%, 2/5

Put the following in order of size, smallest to largest:  
2/5, 9/25, 0.371, 38%  


Oh dear, looks you like have a brain like a sieve. Factors, fractions, formulas – it's all the same to you i.e. stuff you have no clue about! You've got bigger things on your mind and it ain't maths.

Not bad at all! A few of these pesky questions may have stumped you, but I think it's fair to say you've maintained a pretty good grasp on maths from your school days. Congrats on being a relative brain box!

Okay wow... you are either someone who does a lot of daily mathematics or you have an impeccable memory! You aced this test and proved when it comes to maths, you still got it!
