Basic Math Formulas: Addition, Subtraction & Multiplication

Introduction

• Basic math formulas are essential tools not only in academic learning but also in everyday life.
• These formulas cover addition, subtraction, multiplication, and more, applicable from primary classes to higher education.
• The BODMAS rule is a fundamental concept that helps in solving equations systematically.

Importance of Basic Math

• Basic math provides solutions to real-world problems using equations.
• It ranges from simple addition formulas to more complex integrations and differentiations.
• Useful in various fields such as physics (forces, acceleration), economics, statistics, etc.

Basic Math Formulas List

• Proportion: Product of extremes equals the product of means, i.e., ( ad = bc ).
• Percentage Formula:
  • Rate: Percent value.
  • Base: The amount taken for percentage calculation.
  • Percentage: Obtained by multiplying the base by the rate.

Example Problems

Problem 1

• Find x if 1/5 = 2/x.
  • Cross multiply to get: ( x = 10 ).

Problem 2

• Add the fractions 2/5 and 6/7.
  • LCM of 5 and 7 is 35.
  • Equivalent fractions: ( 2/5 = 14/35 ) and ( 6/7 = 30/35 ).
  • Sum: ( 14/35 + 30/35 = 44/35 ).
