Number System | Maths | SSC TARGET BATCH | Ravish Mishra | SSC CGL CHSL MTS GD CPOSI etc.

Описание: This video, part of the "Number System" series for SSC TARGET BATCH, focuses on solving problems related to the addition, subtraction, and multiplication of numbers. The instructor, Ravish Mishra, aims to take students from a "zero to hero" level in mathematics (0:38).

The session covers the following key topics:
Basic Algebraic Identities (4:22): The instructor introduces fundamental algebraic formulas such as:
(x + y)² = x² + y² + 2xy (4:25-4:30)
(x - y)² = x² + y² - 2xy (4:34-4:42)
(x + y)² + (x - y)² = 2(x² + y²) (4:47-5:00)
(x + y)² - (x - y)² = 4xy (5:03-5:06)
Solving Problems Based on Sum, Difference, and Product (5:31): Several examples are worked through, including:
Finding the difference between two numbers given their sum and product (5:31-11:41).
Finding the product of two numbers given their sum and difference (11:48-13:52).
Determining two numbers and their properties based on their product (14:32-18:16).
Problems Involving Ratios (18:19): The video explains how to find the difference between two numbers given their sum and ratio (18:19-20:43).
Sums and Differences of Squares (20:48): The instructor demonstrates how to find numbers when their sum and the difference of their squares are given, utilizing the a² - b² formula (20:48-26:17).
Problems with Reciprocals (31:58): The concept of reciprocals is introduced, and methods for finding the sum of reciprocals (31:58-34:53) and two numbers given their sum and the sum of their reciprocals (35:05-36:58) are explained.
Advanced Problems with Three Numbers (37:28): The video concludes with a complex problem involving the sum of three numbers, the sum of their squares, and finding the difference between the sum of their cubes and three times their product, using advanced algebraic identities (37:28-45:52).
The Number System is one of the most important foundations of Maths, shaping how students understand quantities, values, and calculations in everyday life. From early learning to advanced problem-solving, the concept of a Number helps learners make sense of the world around them. Whether counting objects, measuring distance, or managing money, numbers play a vital role in logical thinking and decision-making.
