Arithmetic Operators Flashcards

1️⃣ Familiarise yourself with the flashcards:

Look through all the flashcards to see what's on both sides.
Make sure you understand the information on each card. If something's unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

Look at the question or prompt on each card and try to remember the answer before flipping it over.
Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It's useful to remember specific examples to understand these concepts better.

What does the + operator do?

It adds numbers. Example: 3 + 4 = 7.

It subtracts one number from another. Example: 9 – 2 = 7.

It multiplies numbers. Example: 5 * 6 = 30.

It divides numbers and can give a decimal answer. Example: 7 / 2 = 3.5.

It does integer division and gives the whole number part only. Example: 7 DIV 2 = 3.

It gives the remainder after division. Example: 7 MOD 2 = 1.

It raises a number to a power. Example: 2 ^ 3 = 8.

They make that part work first. Example: (2 + 3) * 4 = 20.

Brackets, Indices (powers), then Division and Multiplication, then Addition and Subtraction, left to right.

Work from left to right. Example: 20 / 5 * 2 = 4 * 2 = 8.

The / operator gives a decimal result; DIV gives the whole number part only. Example: 9 / 4 = 2.25, 9 DIV 4 = 2.

You cannot divide by zero. It is not allowed, so the program gives an error.
