This quiz poses questions on basic probability and statistics.

Students seem to not realise that $\frac{a}{b}\times c=c\times\frac{a}{b}=\frac{a\times c}{b}=\frac{c\times a}{b}=a\times c \div b=a\div b\times c=c\div b \times a \ne c \div (b\times a)\ldots $ etc. This question is my attempt to help rectify this.

Find the determinant and inverse of three $2 \times 2$ invertible matrices.

This question tests the students ability to factorise simple quadratic equations (where the coefficient of the x^2 term is 1) and use the factorised equation to solve the equation when it is equal to 0.

Given two numbers, find the gcd, then use Bézout's algorithm to find $s$ and $t$ such that $as+bt=\operatorname{gcd}(a,b)$. 

Use laws for addition and subtraction of logarithms to simplify a given logarithmic expression to an arbitrary base.

Crear una tabla de verdad para una expresión lógica de la forma :

                $( a \ {op1} \ b) \ {op2} \ (c \ {op} \ d) \ {op4} \ e $

donde cada una de $a, \; b, \; c, \; d, \; e, \; f $ puede ser una de las variables booleanas $ p, \; q, \; \neg q, \; \neg p $ y cada uno de los operados $\{op}$  puede ser uno de los operadores $\lor, \; \land, \; \to$.

Dados los primeros y últimos términos de una secuencia aritmética finita, calcule el número de elementos y luego la suma de la secuencia.

Cada parte se divide en pasos, con la fórmula dada.

Create a truth table for a logical expression of the form $(a \operatorname{op1} b) \operatorname{op2}(c \operatorname{op3} d)$ where $a, \;b,\;c,\;d$ can be the Boolean variables $p,\;q,\;\neg p,\;\neg q$ and each of $\operatorname{op1},\;\operatorname{op2},\;\operatorname{op3}$ one of $\lor,\;\land,\;\to$.

For example: $(p \lor \neg q) \land(q \to \neg p)$.

Given two numbers, find the gcd, then use Bézout's algorithm to find $s$ and $t$ such that $as+bt=\operatorname{gcd}(a,b)$. Finally, find all solutions of an equation $\mod b$.

Differentiate between linear and quadratic sequences and arithmetic and geometric sequences through a series of multiple choice questions. Spot different patterns in sequences like the triangle sequence, square sequence and cubic sequence and then use this pattern to find the next three terms in each of the sequences.
