Obtuse triangle
Obtuse triangle An obtuse triangle or obtuse-angled triangle is a type of triangle that has one obtuse (greater than 90°) angle. As the sum of all the interior angles of a triangle is 180°, an obtuse-angled triangle has one obtuse angle and two acute angles (less than 90° each). An obtuse triangle is like this: […]
Negative number
Negative number A negative number is a number whose value is always less than zero and it has a minus (-) sign before it. On a number line, negative numbers are represented on the left side of zero. They can be integers, decimals, or fractions. For example: -7, -24, -3/5, -0.8 are termed as negative numbers. Here […]

Used for counting 1, 2, 3…. or ordering 1st, 2nd, 3rd… Counting numbers are more often called the natural numbers. The symbol N represents the set of natural numbers.N{ 1, […]
Commutative law
Commutative law The definition of commutative law states that when we add or multiply two numbers then the resultant value remains the same, even if we change the position of the two numbers. It means that you can swap numbers around and still get the same answer when you add or when you multiply. Examples: Addition […]
