Class 7 Maths कक्षा 7 गणित

Unlimited Class 7 maths practice: integers, fractions and decimals, data handling, simple equations, lines and angles, triangles and Pythagoras, comparing quantities, rational numbers, perimeter and area, algebraic expressions and exponents, with hints and worked steps.

Integers

Multiply and divide integersSame signs give a positive answer, different signs give a negative one. An even number of negatives makes the product positive.

Fractions and decimals

Data handling

Mean and range of dataMean (average) = sum ÷ number of values. Range = highest − lowest.

Simple equations

Solve simple equationsUndo the operations in reverse order, doing the same thing to both sides.

Lines and angles

Complementary, supplementary and vertically opposite anglesComplementary angles add to 90°, supplementary angles (and a linear pair) add to 180°. Vertically opposite angles are equal.

The triangle and its properties

Comparing quantities

Rational numbers

Rational numbers in standard form and their sumStandard form: denominator positive, numerator and denominator with no common factor. To add, use a common denominator.

Perimeter and area

Algebraic expressions

Add and subtract algebraic expressionsOnly like terms (same letters with the same powers) can be combined: add or subtract their coefficients.

Exponents and powers

Exponents and powersaⁿ means a multiplied by itself n times. aᵐ × aⁿ = aᵐ⁺ⁿ and (aᵐ)ⁿ = aᵐⁿ.
