A Math Olympiad is a prestigious mathematics competition for high school students. The competition usually involves solving complex and challenging mathematical problems that require critical thinking, problem-solving skills, and creativity. The problems are designed to test the student’s ability to apply their knowledge of mathematics to real-world situations, as well as their ability to think outside the box and develop innovative solutions.
Math Olympiad competitions are typically held at local, national, and international levels, and participants are selected through a rigorous screening process. The competition is a great opportunity for students to showcase their mathematical abilities and compete with other talented students from around the world.
Participating in Math Olympiad competitions can help students improve their problem-solving skills, boost their confidence, and develop a passion for mathematics. It can also open doors to exciting opportunities such as scholarships, internships, and research positions in mathematics-related fields.

IMO Class 5 Chapter 3:Addition and Subtraction of Decimal Numbers Detailed Notes
Comparing operations on decimals to those on natural numbers reveals that adding and subtracting decimals is a little more difficult. Let’s first grasp decimals before learning how to add or subtract any two or more than two supplied decimals. More precisely than integers or whole numbers, decimal numbers are used to represent numbers. It employs a dot, referred to as a decimal point, between each number. The only difference between decimals and fractions is their simplification. Check out these fractional decimal issues.
For instance, we cannot express the pies that each child received in terms of integers alone when we must split three pies among four children because each child received pies that range from 0 to 1. The idea of decimals was developed to address other issues of a similar nature. Decimal addition, multiplication, division, and subtraction is a hence crucial concept. Let’s imagine that two pals are chipping in to purchase an Rs. 20 cricket ball. The difference between the two of them is Rs. 7.50 and Rs. 18.50. They need to understand the idea of addition and subtraction of decimals in order to determine how much money they will need to donate and how much money they will have remaining after contributions.
Adding Decimal Places
Numbers can be added, subtracted, multiplied, and divided, as is common knowledge. However, natural numbers make all of these operations simple to carry out. Addition with decimals can be carried out in a particular way. There are various steps involved in adding decimals.
How to Add Decimals?
In order to add decimals, use the following steps:
Step 1: Depending on how many digits after the decimal any given number can have, it is initially padded with zero.
Step 2: The numbers are arranged vertically next to one another as seen in the figure below.
Step 3: Add the decimal numbers that are analogous to integers, then set the decimal point appropriately.
Examples of adding decimals
Let’s look at some examples of decimal addition.
Example 1: find the sum of 1.33 and 1.091.
Example 2: Subtraction 4.1 – 0.94
