Maths concepts
Squares 1 to 30
The squares of numbers from 1 to 30 range from 1² = 1 to 30² = 900. A square number is the result of multiplying a whole number by itself (n × n). The full table of all 30 values is below.
Cubes 1 to 20
The cubes of numbers from 1 to 20 range from 1³ = 1 to 20³ = 8000. A cube number is a whole number multiplied by itself three times (n × n × n). The full table is below.
Prime Numbers 1 to 100
There are 25 prime numbers between 1 and 100: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97. A prime number is a whole number greater than 1 with exactly two factors — 1 and itself.
Properties of a Trapezium
A trapezium is a quadrilateral with exactly one pair of parallel sides. Those parallel sides are the bases; the other two are the legs. Its area is ½ × (sum of the parallel sides) × height, and its four interior angles add up to 360°.
Square Root of 1024
The square root of 1024 is 32, because 32 × 32 = 1024. Since 1024 is a perfect square, its square root is a whole number.
