Algebraic Expressions Introduction: An operator is a symbol that shows a mathematical operation. For example, the symbols, “+”, “-”, “*”, “/” ; describe what we want to do with the values, wherever above symbols are present. A term is either a variable or a single number, or variables and numbers multiplied together. For example: X, 2X, 3Y or 5. When an operator is put in between two […]
PROFIT AND LOSS We often hear and use the term and concept of Profits and Losses in our everyday life. For example, a shopkeeper sells a pen at Rs.6 whereas it cost him Rs.5. then the shopkeeper is making a profit of Rs.1. Profit and Loss chapter is an important chapter in business as it […]
Fractions: Fractions Scaling Fraction scaling is just a fancy way to say resize or resizing. In our real world, sometimes we need to scale or resize several things like photograph, maps etc. FOLLOW THE ATTACHED ARTICLE TO UNDERSTAND FRACTIONS AND SCALING METHODS. Attachments : M5-1.4.4
ALGEBRA Algebra is a branch of study in mathematics that deals with relations and operations. We know that a mathematical expression uses mathematical symbols instead of words. For example, the words ‘twenty-eight increased by five’, will be shown as the mathematical expression 28 + 5. If we say there were some people at a party and 7 […]
CIRCLES, TRIANGLES AND NETS Geometry is a branch of mathematics concerned with questions about shape, size, relative position of figures, and the properties of space. It is all about shapes and their properties. In this chapter of geometry, we will learn about Circles, its parts and how to construct a circle; Triangles and […]
LINES AND PLANES Lines and planes are basic topics covered in Geometry till now. However, we will expand our theory to angles. Angles and lines are important not only in theory but in practical life be it in the field of architecture or astronomy. In this chapter we will learn the concept of angles […]
AREA AND VOLUME Area and volume is a very vast topic to cover. In real life, we come across discussions related to area covered by a building or capacity of a container. The volume of a material of metal shows how precious the metal is. Therefore, it is an important chapter not only for […]
Measurement of Capacity The maximum amount that something can hold is called it’scapacity. The standard unit of capacity is litre. Millilitre, centilitre, decilitre are smaller unit used to measure smaller capacity, litre is commonly used to measure capacity, whereas units like decalitre, hectolitre and kilolitre are used to measure larger capacity. All these units are related […]
Measurement of Weight Standard unit of weight is kilogram. We commonly use grams and kilograms to measure weight. Gram is the basic/standard unit of weight which is written as ‘g’. All units of weight are related to each other. We measure small weights in cg and mg and large weights g and kg. […]
Addition of Metric Measures Metric measures are added in the same way as we add whole numbers or decimals. We arrange the digits in columns as per their unit and then add as required. Let us consider an example. Example- Add 4 km 9 hm 3 m 5 cm, 3 km 8 dam 2 dm […]
