Quotient
Quotient The number we obtain when we divide one number by another is the quotient. For example, in 10 ÷ 5 = 2. The result of the division is 2, so it is the quotient. 10 is the dividend and 5 is the divisor. Note that the quotient and the divisor are always smaller than […]

Width
Width Width measures an object from one side to another. For example, we tell how wide a road is by measuring the distance from one side of the road to the other. Width – shorter side of the shape, and it shows how broad or wide the given figure is. Lenght – longer side of the […]
Perimeter
Perimeter The perimeter of a 2D shape is the total length of all its sides. For example, a rectangle has four edges, so its perimeter is the total of those four edges added together. Some more examples about how to calculate the perimeter of some shapes: P = 9+8+5 = 22 cm P = […]
Percent, percentage
Percent, percentage Percent means “for every 100 parts“. The word comes from the latin phrase per centum which means per one hundred. Percentage means a part per hundred. It can be expressed in decimal form and in fraction form too. A percentage of a number is symbolized by writing: Examples: If we say 30%, it means 30 out […]

Operations
Operations Operations of integers are all the mathematic acts that happen under defined conditions. In maths, there are 4 basic rules that can solve anything. These are Addition and Subtraction are inverse operations Multiplication and Division are inverse operations Integers mean a whole positive or negative number. But It can’t be both at the same […]
