⚡ Veda Bites

The whole idea, one bite at a time

Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.

💡 Key Idea

The integers carry a direction

Numbers that run both ways

A temperature can be above or below zero, and a balance can be in credit or in debt.

💡 Key Idea

One blue and one red together

A pair worth nothing

Take blue counters for positives and red for negatives. One of each is worth nothing at all.

💡 Key Idea

Cancel, then read what is left

Adding with counters

Put out counters for each number, then cancel every zero pair you can see.

💡 Key Idea

And that reading survives a negative

Multiplying is repeated adding

For whole numbers, 3 times 4 means three lots of 4, which is 12.

🚫 Warning

There is no doing something minus three times

The other order is awkward

Taking -3 times 4, the repeated adding reading breaks down.

💡 Key Idea

It never did for whole numbers

The order should not matter

Three times 4 and 4 times 3 both give 12, and swapping never changes a product.

📖 Smart notes

What you'll study, topic by topic

1

Adding and subtracting integers with counters

A blue counter and a red counter make a zero pair, worth nothing, so adding or removing pairs changes no total. To add, cancel every zero pair and read what is left. To subtract something absent, add zero pairs first, wh…

  • The integers are the whole numbers together with their negatives.
  • Zero takes neither a plus nor a minus sign.
  • One blue counter with one red counter is a zero pair, worth nothing.

Multiplying integers, and why two negatives give a positive

Multiplying by a negative extends repeated adding, and a pattern running past zero forces every value, including the one where both numbers are negative. Removing groups of red counters agrees. A product is negative exac…

  • Three lots of -4 is -12, so repeated adding survives one negative.
  • Swapping the two numbers never changes a product, which settles -3 times 4.
  • In the column from 3 times 2, each answer is 3 less than the one above.

Dividing integers, and the sign rule they share

A division asks which number multiplies the divisor to give the dividend, so it is a multiplication question in disguise and needs no second sign rule. A quotient is negative when the signs differ. Dividing may give no i…

  • A division asks which number multiplies the divisor to give the dividend.
  • So every division is a multiplication question with a gap in it.
  • Minus 12 divided by 3 is -4, and 12 divided by -3 is -4 as well.

❓ Leveled MCQ practice

Try the smart MCQs from this kit

105 questions laddered from warm-up to topper-level, each with an explanation. A taste:

A set of numbers is built by taking the whole numbers and then adding something to the collection. The integers are the whole numbers together with

Beginner
A their negatives B the fractions C the decimals D their halves
Show answer & explanation

their negatives

And zero takes neither sign.

A number is written down with a minus sign standing in front of it rather than a plus sign. Such a number is

Beginner
A negative B positive C zero D a fraction
Show answer & explanation

negative

So -8 is eight in the downward direction.

Among all the integers there is one that is neither above nor below the dividing point. The number taking neither sign is

Beginner
A one B minus one C zero D every whole number
Show answer & explanation

zero

It has no direction at all.

One blue counter is placed on the table and one red counter is placed beside it, and the two are valued together. Together they are worth

Beginner
A two units B nothing at all C one unit D minus one unit
Show answer & explanation

nothing at all

They pull opposite ways by the same amount.
