Please Could someone tell me what:
1. A square number is
2. A cube number is
3. A triangle number is
Square numbers are the result of squaring an integer (IxI)
Cube numbers are the result of the cube of an integer (IxIxI)
A triangular number is a number such that the shape of an equilateral triangle can be formed by the number of dots.
Difficult to draw here, but the first three are 1,3,6 as
Is this OK? Next one is?
Oops the dots didn't work.
I usually illustrate triangular numbers with the example of setting up a triangle of billiard balls
with 1 row you have 1 ball
with 2 rows you have 3 balls
with 3 rows you have 6 balls
with 4 rows you have 10 balls
