What Class 10 Mathematics covers

One thing each chapter sets out to make you able to do, in the order the book teaches them.

Generate composite numbers by multiplying a chosen set of primes with repetition, and explain why that process alone never proves the reverse directionCh 1Real Numbers
Identify the degree of a polynomial in one variable by locating the largest power of that variable which actually appearsCh 2Polynomials
Turn a stated situation into two equations by naming the two unknown counts and writing one equation per conditionCh 3Pair of Linear Equations in Two Variables
State the four conditions the standard form imposes: one variable, real coefficients, highest power exactly two, and a leading coefficient that is not zeroCh 4Quadratic Equations
State what has to be true of a list of numbers for it to be called an arithmetic progression, in terms of the difference between neighbouring entriesCh 5Arithmetic Progressions
State the difference between two figures being congruent and being similar, in terms of which of shape and size is being held fixedCh 6Triangles
Say which axis each of the two coordinates is measured from, and use the printed names abscissa and ordinate correctlyCh 7Coordinate Geometry
Identify the hypotenuse of a right triangle from the position of the right angle alone, without measuringCh 8Introduction to Trigonometry
Identify, in a described or drawn situation, the observer's eye, the point of the object being aimed at, and the ray joining themCh 9Some Applications of Trigonometry
Sort a line drawn against a circle into one of exactly three kinds by counting the points the two shareCh 10Circles
Distinguish a sector from a segment by naming what bounds each oneCh 11Areas Related to Circles
Look at a drawn or described object and name the basic solids it is assembled from, and how many of eachCh 12Surface Areas and Volumes
Compute the mean of an ungrouped frequency distribution as Σf·x ÷ Σf, laying the products out in a columnCh 13Statistics
State what is being assumed when a coin is called fair, and separate that from what is being assumed when the toss is called randomCh 14Probability

Where students most often slip up

Sentences students actually say, one from each chapter, taken from the notes the videos were made from.

"The theorem just says numbers can be factorised."Ch 1Real Numbers
"Degree counts the terms."Ch 2Polynomials
"An equation has an answer, so this one has an answer."Ch 3Pair of Linear Equations in Two Variables
"It has an x², so it is quadratic."Ch 4Quadratic Equations
"AP means the numbers get bigger."Ch 5Arithmetic Progressions
"Similar means roughly alike."Ch 6Triangles
"The x-coordinate is the distance from the x-axis."Ch 7Coordinate Geometry
"BC is the opposite side, full stop."Ch 8Introduction to Trigonometry
"The angle is measured up from the ground."Ch 9Some Applications of Trigonometry
"A tangent is a line that touches but does not cross."Ch 10Circles
"A segment is the same as a sector, roughly."Ch 11Areas Related to Circles
"There must be a formula for a top / a capsule / a rocket."Ch 12Surface Areas and Volumes
"One of 59.3 and 62 is a mistake."Ch 13Statistics
"Two possible results, so each has probability one-half."Ch 14Probability
