Mathematics is one of the subject areas in which students must master concepts. Thorough practice is one of the most important aspects of mastering mathematics, and the International Maths Olympiad (IMO) is one such platform where students are trained to understand its fundamentals. IMO Class 3 Chapter 2 Addition Subtraction Multiplication Division

International Maths Olympiad is held by School Connects Online. It is open to students in grades 1 to 10. All of the questions on these exams are multiple-choice. The Olympiad exam also serves as a foundation for students to achieve academic success. It gives students an advantage over their peers when solving difficult questions.

IMO Class 3 Chapter 2: Addition, Subtraction, Multiplication, Division Detailed Notes

Arithmetic is the fundamental branch of mathematics that derives from the Greek word arithmos, which means “number.” The numbers are being studied, and operations such as addition, subtraction, division, and multiplication are being performed.

Operations with numbers

Addition, subtraction, division, and multiplication are all arithmetic operations.

Addition (+)

The other fundamental operation in Arithmetic is addition. It refers to combining two or more values to form a single term. For e.g., 1+3 = 4.

The identity element of addition is 0, which means that adding 0 to any value yields the same result. The inverse of any value is the opposite element of addition, which implies that keeping the opposite of any digit to the digit itself gives the additive identity.

 Subtraction (−)

Subtraction is known as the inverse of addition. It calculates the difference between two values, i.e. the minuend minus the subtrahend. The difference is positive if the minuend is more prominent than the subtrahend. The outcome is negative if the minuend is less than the subtrahend.

Multiplication  (×)

Multiplication, like addition and subtraction, connects two values into a single value, or the product. The multiplicand and multiplier are the two distinct values. The product of a and b is represented as ab or a x b.

Division  (÷)

The inverse of multiplication is division. It computes the quotient of two numbers, the dividend divided by the divisor. If the dividend is greater than the divisor for any well-defined positive number, the quotient is greater than one.

How to Get Ready for a Math Olympiad

Preparation is especially important when a student is taking a competitive exam, such as the International Math Olympiad.
