List five integers that are congruent to 4 modulo 12.

The aim of this question is to introduce the concept of congruency of an integer with another integer under some modulo. Whenever we divide one integer over another, we have two results, namely a quotient and a remainder. The quotient is the part of the result that defines the perfect division while the existence of […]

Show that the product of a number and seven is equal to two more than the number.

The aim of the given question is to introduce word problems related to basic algebra and arithmetic operations. To solve such questions we may need to first assume the required numbers as algebraic variables. Then we try to convert the given constraints into the form of algebraic equations. Finally, we solve these equations to find […]
