Class 7 Maths Olympiad Questions & Sample Papers

The term integer is a wide concept that includes various things, including the natural number and whole number.

Natural numbers are numbers that start from 1 and move on. In comparison, the whole numbers are the set of numbers that start from 0 and move on.

The term decimal refers to the number system that helps in expressing the fraction & whole numbers. The number present in the decimal consists of a ‘.’ symbol in it. In comparison, the term fraction refers to a number system always presented in the form of a / b.

When we have to convert the decimal number to a fraction, we have to remove the dot, i.e., 1.5 is a decimal number, and when we convert it into a fraction, it will be 15/10, i.e., 3/2. Or 2.5 is a decimal number, whereas 25/10 is a fraction. And it is equal to 5/2.

The term exponents refer to the expanded form of a number, such as 2 x 2 x 2 x 2. At the same time, power refers to a short version of that expanded form, such as 2^4. This whole expression,i.e., 2^4, is called the power.

The term algebraic expression refers to the expressions available in the form of variables. These are the complete set of operations, including addition, multiplication, division, and subtraction. Example 2x + 5 is known as an algebraic expression.

The term simple linear equation refers to the expression that includes the different sets like variable, constant, and operations.

These operations include multiplication, addition, and other terms. The term variable consists of the symbols not present in the fixed values. Example: 2x + 5, in this x is known as the variable.

Both lines & angles are two different terms.

The line means a straight part of a line. In contrast, an angle means the sequence between two lines.

Every day, we are faced with the challenge of comparing two quantities. It could be height, weight, salary, grade, and so on. If two quantities are to be compared, their units need to be the same.

Comparing quantities refers to a quantitative relationship between two quantities that reflects their relative size. This is simply a method for comparing the quantities.

Triangle is a three-figure term that is a closed figure.

It consists of three sides, angles, and vertices. We can see that triangles are of different types. All these types of triangles vary from one another.

The term symmetry refers to the shape of a particular object divided into equal parts.

In the symmetry form, one half of the mirror image is considered as the other half.

The term triangle refers to a closed figure that includes three sides, vertices, and angles.

The congruent triangles are always equal in shape. Different properties state the unity of a triangle.

Rational numbers are the number set that includes many numbers in the form of p/q, in which q is not equal to 0. This set of numbers, whether natural numbers, whole numbers, integers, or any.

The term perimeter refers to the coverage of the length of a figure from the outside. At the same time, the area is known as the object's surface. For different sets of figures, there are different formulas.

The term data handling includes various terms like a collection of data, range, frequency, mean, median and mode. The collection of data will make everything clear. But before the collection of data, we must need specific details about the concept.

Suppose we collect the data of class students, then we must know their actual performance. And how they deal with it.

Visualising solid shapes consist of 2D and 3D shapes. These shapes are the different sets that include faces, edges, and vertices. Some examples of solid shapes are cube, cylinder, cuboid, cone, sphere, etc.

Practical Geometry includes various terms like a line segment, perpendicular lines, construction areas, triangle construction, etc.
