What is order of operations and how do you use them in equations?

Let’s start at the beginning.

## What is an operation?

An operation means to add, subtract, multiply, divide, squaring, etc.

When you see something like this:

Parallel structure, also called parallel construction, is the repetition of a grammatical form within a sentence. Staying with one form adds clarity to your writing.

For example:

**Harry likes swimming, the theatre and to go for hikes. – not parallel**

Harry likes swimming, attending the theatre and hiking. – parallel

Or

Harry likes to swim, attend the theatre and hike. - parallel

All numbers are built from prime numbers. “Factors” are the numbers you multiply to get another number.

For example

“Prime factorization” is finding which prime numbers multiply to make the original number.

‘Apart’ and ‘a part’ are often confused as they sound the same when you say the words. Despite their similar sounds, the two have very different meanings.

## When to use 'apart'

Apart’ is an adverb that means two or more people or things separated by a distance; or at a distance from each other in space or time.

For example:

- The towns are fifty miles apart.
- As they got older, the two friends grew apart.
- The puzzle has been taken apart.

Apostrophes are used:

to indicate possession or ownership,

in contractions,

and in plurals.

## Use of apostrophes to indicate possession or ownership

To indicate the possession of something you add an ‘apostrophe and s’ at the end of of the noun; that’s the case for plural nouns that don’t end in an s as well.

For example:

Singular:

Susan’s doll is wearing a yellow dress.

Plural:

The children’s rooms are messy.

You may have heard of measuring the area and the perimeter of shapes. But what exactly are they?

Perimeter is the measure of distance around a shape. For example, the distance around a soccer field.

Area is the measure of the surface something covers. For example, the space in which you pour batter in a cake tin for baking in the oven.

Kids are often afraid to use the words ‘me’ and ‘I’, as they get them the wrong way around. So what do they do? They substitute me and I with ‘myself’, making the grammar mistakes a whole lot worse.

Here are some hard and fast rules for how to use me, myself and I – and how not to use them.

## Use I for the subject

I is used when the subject of a sentence.

I like to paint pretty flower.

I walk the dog every day.

I love to cook using new recipes.

## Use me for the object

Me is used when the object of a sentence.

He gave the flowers to me.

She knew how to make me happy.

The teacher gave me my homework.

Proper fractions are fractions where the numerators are less than the denominators. For example, 3/5 or 4/7.

When multiplying fractions, you apply the following rule:

## 1. Multiply the top numbers – the numerators

Subjunctive verbs are complicated – when do you use ‘I was’ and when do you use ‘I were’ when you express a wish or command that is not real or factual?

For example – do you say?

I wish I was a princess living in a pink castle. – Incorrect

Or

I wish I were a princess living in a pink castle. – Correct
