15 terms you’ll see on your child’s maths homework – and what they mean

We’ve all been there. The little ones ask for some assist with their homework, you confidently agree however as quickly as you decide up the worksheet you possibly can barely perceive the question – not to mention work out the answer.

But worry not. If you are attempting to wrap your head round maths terminology, you are not alone. We’ve put collectively a information of 15 frequent phrases you are more likely to see on your child’s homework and – extra importantly – what they mean.

So sharpen your pencil and dig out the protractor as a result of we’re going that can assist you over this homework hurdle.

1. Geometry

Okay so we’ve all heard of it however what precisely is geometry? It’s not truly too sophisticated. Put merely, geometry is the examine of traces, angles, shapes, and their properties. Geometry research bodily shapes and the item dimensions.

Flat-like squares, circles, and triangles are part of flat geometry and are known as 2D shapes. These shapes have solely two dimensions – the size and the width. Solid objects are also referred to as 3D objects having the third dimension of peak or depth.

2 . Algebra

It’s not one thing you’d discover within the lingerie aisle in M&S – algebra is the department of arithmetic that substitutes letters for numbers to unravel for unknown values. Remember this kind of factor in school: x-2 = 4. When you don’t know the quantity, you utilize a letter as a substitute (as a result of it’s manner simpler than drawing a clean field).

3. Pythagoras

You may assume it’s a dish accessible at your native Greek restaurant however it’s one thing simply as tasty for maths lovers. Pythagoras’ theorem is a formulation you should use to calculate the size of any of the edges on a proper-angled triangle or the space between two factors. Might even be accompanied by “hypotenuse” (the longest aspect of a proper-angled triangle, at all times reverse to the best angle itself.)

4. Calculus

While it could sound like a medical situation for one thing that grows on your foot, calculus is the department of arithmetic involving derivatives and integrals. It’s the examine of movement by which altering values are studied and anybody who masters it’s, fairly frankly, quite intelligent.


This is an acronym used to assist folks keep in mind the right order of operations for fixing algebraic equations. BEDMAS stands for “Brackets, Exponents, Division, Multiplication, Addition, and Subtraction”. You may additionally see PEMDAS which stands for “Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction”.

6. Pi

We’ve all studied it in school and it in all probability makes you hungry each time you see the world however it’s nothing to do with meals. Pi is used to symbolize the ratio of a circumference of a circle to its diameter and is denoted with the Greek image π.

7. Nth root

You could possibly be forgiven for considering that is one thing to do with the date or perhaps a tooth extraction however it’s not. The nth root of a quantity is what number of instances a quantity must be multiplied by itself to attain the worth specified.

So – the 4th root of three is 81 as a result of 3 x 3 x 3 x 3 = 81.

8. Algorithm

It’s the kind of phrase that sends shivers down spines however preserve calm and breathe as a result of it’s not all that dangerous. It’s truly a complicated phrase for a process or set of steps used to unravel a mathematical computation.

9. Coefficient

This has nothing to do with whether or not you’re employed properly in a group. The coefficient is a letter or quantity representing a numerical amount connected to a time period (often initially).

For instance, x is the coefficient within the expression x (a + b) and 3 is the coefficient within the time period 3y.

10. Congruent

Put merely, congruent is objects and figures which have the identical measurement and form. Congruent shapes could be was each other with a flip, rotation, or flip. See? Maths doesn’t need to be sophisticated!

11. Fibonacci

If what this implies, it’s the kind of data that might work properly in a pub quiz. A Fibonacci sequence is a sequence starting with a 0 and 1 whereby every quantity is the sum of the 2 numbers previous it. So, for instance, “0, 1, 1, 2, 3, 5, 8, 13, 21, 34…” is a Fibonacci sequence.

12. Hyperbola

It appears like some tropical illness however it’s a kind of conic part or symmetrical open curve. The hyperbola is the set of all factors in a airplane, the distinction of whose distance from two mounted factors within the airplane is a constructive fixed.

13. Isosceles

If you’re a whizz at geometry, you’ll have realized about this – it’s a polygon with two sides of equal size. Weirdly, we at all times consider pizza once we are picturing it in our head.

14. Median

The median is the “middle value” in a collection of numbers ordered from least to best. When the full variety of values in an inventory is odd, the median is the center entry. When the full variety of values in an inventory is even, the median is the same as the sum of the 2 center numbers divided by two.

15. Prime

We may solely use this once we’re referring to good outdated Amazon TV however lecturers use it as a result of prime numbers are of big significance in maths.

Prime numbers are integers better than 1 which are solely divisible by themselves and 1 – comparable to 2, 3, 5, 7, and 11.
