## What is numerical reasoning?

Assessments are usually composed of three parts: abstract, numerical and verbal. However, the components that you can expect per test differ greatly. Both in terms of what is expected in skills and how your score is built up.

Numerical reasoning measures how good you are in linking up with abstract information that is represented by numbers. This can be done by means of number series where you have to recognize a pattern in a series. In addition, tables and graphics are widely used. Then you must perform various calculations with the data shown and draw the correct conclusions. This skill is very important for your further career. Think of annual reports or other financial information that you must be able to process quickly and draw the right conclusions.

### Number sequence

Part of numerical reasoning. Number sequences are often used in assessments. The idea of a number sequence is that you get to see a few numbers and then have to determine the last number. To determine the last number you will often have to perform simple calculations: addition, subtraction, multiplication, division, fractions, percentages, decimal places, powers.

There are also a number of variations: skipping numbers, increasing or decreasing changes, series of calculations.

### Letter sequence

Letter sequences are similar to number sequences. Only in this case you do not have to determine which number comes in the series, but which letter comes in the series. This mainly concerns the positions of the letters. In the series you will see that letters according to the alphabet increase with certain steps. That is why you should apply simple calculations here and master some simple language skills.

In general, three types of letter sets can be distinguished and some exceptions possible: single and double letter sets, the position of letter sets and other exceptions.

### Word problems

Word problems are part of numerical reasoning. With a word problem, you get to see a number of lines with data in it. You must then answer a question. The tricky thing about editorial sums is that you:

• Determine what needs to be calculated.
• Determine which data is relevant.
• Perform calculation.

The calculation in this case is secondary to the correct interpretation of the information. The disadvantage of assessments is that only the outcome counts. Even if you have reasoned correctly, you may have the answer wrong and you get zero points for that question.

### Mental arithmetic

Mental arithmetic occurs as a unique part of numerical reasoning. In addition, in a broader sense, calculation skills are needed as a basis for numerical reasoning. The maths component is tested with sums. Calculations to be performed are: addition, subtraction, multiplication, division, fractions, percentages, decimal places and estimates.

There is often an overlap with the editorial sums section (also called story sums). In this case, you will see a sentence or two with a question. You must then consider which data is required and which calculation must be performed.

The limitations of calculating skills are the limitations. For example, you are usually not allowed to use a calculator, but you can use scrap paper. You also have to answer a lot of questions in a short time. It is therefore important that you can do good mental arithmetic.

### Tables and graphs

Tables, or calculating with tables, is part of numerical reasoning. This form of numerical reasoning is very popular in assessments. The advantage is that different skills are tested. You must not only be able to count, but you must also be able to process information and draw logical conclusions. The following should always be done with a table or graph:

• Determine what needs to be calculated.
• Determine which data is relevant.
• Perform calculation.

The calculation in this case is secondary to the correct interpretation of the information. The disadvantage of assessments is that only the outcome counts. Even if you have reasoned correctly, you may have the answer wrong and you get zero points for that question.
