Integers
In order to ace your trading interview it is essential to get the basics right. We offer standard arithmetic operations with integers and adjust the question and answer type depending on the company that you want to prepare for.
- $$-66 + 105 =$$
- $$5 \times 18 =$$
- $$109 - 46 =$$
- $$170 \medspace/\medspace 5 =$$
Decimals
Mastery of arithmetic operations with decimals is vital for aspiring traders. Our practice sets include precisely those variations that are relevant for trading interviews.
- $$0.16 + 23.01 =$$
- $$2.5 \times 0.09 =$$
- $$-6.63 - 3.593 =$$
- $$21 \medspace/\medspace 0.7 =$$

- $$0.16 \times 23812 =$$
- $$42.5 \times 1.04 =$$
Fractions
The '80 in 8' test employed by Optiver includes various types of computations with fractions. Our Orange Test allows you to familiarize yourself with such questions and save you valuable seconds during your numerical test.
- $$\frac{4}{9} + \frac{10}{27} = \text?$$
- $$\text? \times \frac{1}{8} = 2$$
- $$\frac{3}{9} - \text? = \frac{5}{18}$$
- $$\frac{2}{20} \medspace/\medspace \frac{1}{5} = \text?$$
