All you need to find is the different groups which equal 18. For example;

18/2=9 so two groups of 9

18/3=6 so three groups of 6

18/6=3 so 6 groups of 3

18/9=2 so 2 groups of 9

18/6=3 so 3 groups of 6

18/1=18 so 1 group of 18

This is a simple divisional sum and is key in solving mathematical problems. Mathematics is officially the study of quantity, structure, space, and change. Mathematicians seek out patterns and formulate new conjectures accordingly.

This can either by multiplying, subtracting, adding or dividing as in this case. This has harked back even to ancient times to the time of Archimedes. Mathematicians resolve the truth or falsity of conjectures by mathematical proofs, which are arguments sufficient to convince other mathematicians of their validity.

The research required to solve mathematical problems can take a number of years and significant amount of research and sustained inquiry. However, mathematical proofs are less formal and painstaking than proofs in mathematical logic. When those mathematical structures are good models of real phenomena, then mathematical reasoning often provides insight or predictions.

Through these methods that also include abstraction and logical reasoning, mathematics evolved from counting, calculation, measurement, and the systematic study of the shapes and motions of physical objects. One must consider even the initial beginnings of the abacus which was one of the simplest instrument to use when doing maths.

Practical mathematics goes back as far back as written records exist. We use it every day to solve easy problems and numbers are a daily part of our everyday routine. This leads to an understanding and rapid increase in the rate of mathematical discovery that continues even up to today.
