💡 Key Idea
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.
Five steps, one answer
A trick to start with
Think of a number, double it, add four, halve it.
There is always another start
Why trying more will not do
Testing 3, then 11, then 40 never settles the question.
One rule for the whole stack
What a number pyramid is
Each row is one entry shorter than the row below it.
From a full bottom row
Filling one upwards
Add neighbouring pairs to get the row above, and keep going.
Subtract instead of adding
Filling one downwards
If an entry and one beneath it are known, the other is their difference.

Tricks that always land on the same answer
A number trick that ends on the same answer whatever you start from is not magic. Write the steps with a letter and the starting number cancels itself out, leaving only the constant behind.
- Call the starting number a letter and follow it through.
- A trick always lands the same way when the letter cancels.
- What survives the cancelling is the constant alone.

Number pyramids and calendar grids
In a number pyramid each entry is the sum of the two below it. Letters turn a half-filled pyramid into equations, and they also give a formula for the top from the bottom row alone.
- Each entry of a pyramid is the sum of the two below it.
- A known entry and the one beside it give the third by subtraction.
- When nothing can be worked out, put letters in and solve.

The largest product, and divisibility tricks
Algebra settles two kinds of question here. Which arrangement of three digits gives the largest product, and why a trick about reversing digits always divides exactly.
- Three digits fill a two-digit by one-digit product six ways.
- Grouping by multiplier cuts six comparisons down to three.
- The largest digit should be the multiplier.

Try the smart MCQs from this kit
105 questions laddered from warm-up to topper-level, each with an explanation. A taste:
Besides modelling situations and solving for unknowns, the use this chapter makes of algebra is
Beginner
A drawing graphs of the results
B explaining why a trick works
C measuring shapes more accurately
D counting the number of cases
Show answer & explanation
explaining why a trick works
And inventing new tricks of your own.
Think of a number, double it, add four, divide by two, and take away the number you first thought of. The answer you reach is
Beginner
A 4
B the number you started with
C 2
D twice the starting number
Show answer & explanation
2
It is 2 whatever the starting number was.
Trying the trick with 3, then with 11, then with 40 still settles nothing about whether it always works, because
Intermediate
A those three numbers are all of them too small
B the trick has rather too many steps to check
C three cases is an odd number of cases to try
D there are always more starting numbers untried
Show answer & explanation
there are always more starting numbers untried
An argument must cover every start at once.
Taking the starting number as x, doubling it and then adding four gives the expression
Beginner
A x plus 4
B 2x plus 8
C 4x plus 2
D 2x plus 4
Show answer & explanation
2x plus 4
Doubling first, then adding.
