Basic Mathematical Symbols Quiz

A symbol used to indicate equality between two expressions. For example, 5=2+3.

A symbol used to indicate that two expressions are not equal. For example, 5 != 4.

A symbol used to indicate that two expressions are approximately equal. For example, sin(0.01) ≈ 0.01.

A symbol used to indicate that one expression is greater than another. For example, 5>4.

A symbol used to indicate that one expression is less than another. For example, 5<4.

A symbol used to represent the factorial of a number. The factorial of a number is the product of all positive integers less than or equal to that number. For example, 4! = 1 * 2 * 3 * 4 = 24.

A set of numbers where the endpoints are not included. For example, (2; 6) = {x | 2 < x < 6}.

A set of numbers where the endpoints are included. For example, [2; 6] = {x | 2 ≤ x ≤ 6}.

A symbol representing a change or difference. For example, Δt = t1 - t0 represents the change in time.

The symbol used to represent the sum of a series of values. For example, ∑x = x1 + x2 + ... + xn represents the sum of all values of x from 1 to n.

A collection of elements or objects. For example, A = {3, 7, 9, 14} represents a set containing the numbers 3, 7, 9, and 14.

The intersection of two sets contains all elements common to both sets. For example, A ∩ B contains all elements that are in both set A and set B.

The union of two sets contains all elements from either set. For example, A ∪ B contains all elements that are in set A or set B.

A set A is a subset of set B if all elements of A are also in set B. For example, A ⊆ B implies that every element in set A is also in set B.

A set A is a proper subset of set B if all elements of A are also in B, but A is not equal to B (i.e., B contains at least one element not in A). For example, A ⊂ B implies that every element in set A is also in set B, and set B has at least one element that is not in set A.

A symbol used to indicate that one statement implies another. For example, A → B means that if statement A is true, then statement B is true.

A symbol used to indicate that two statements are equivalent or logically interchangeable. For example, A ⇔ B means that statement A is true if and only if statement B is true.

A symbol used to indicate that a statement is true for all values in a set.

A symbol used to indicate that there exists at least one value in a set for which a statement is true.

The rate of change of a function with respect to its input. For example, dy/dx represents the derivative of y with respect to x.

The partial derivative of a multivariable function measures the rate of change with respect to one variable while holding other variables constant. For example, ∂f(x,y)/∂x represents the partial derivative of f with respect to x.

The integral of a function measures the area under its curve. For example, ∫f(x) dx represents the integral of f(x) with respect to x.

A plural noun represents two or more people, places, things, or ideas.

Adding -s or -es to most singular nouns forms their plural forms. Some nouns have irregular plural forms.

The article 'a/an' is used with singular countable nouns, the first time a thing/person is mentioned, when stating what something is, when defining a profession, in exclamations with 'What', and in expressions like three times a week.

The article 'the' is used when referring to something already mentioned, when talking about unique things (like the sun), when the context is clear, with places in a town, and with superlatives.

No article is used when speaking in general (with plural and uncountable nouns), with certain nouns after prepositions (at, to, from), before meals, days, and months, before next/last + days, week, etc., and for continents, cities, or countries.
