Mathematical symbols are a wonderful way of expressing your mathematical ideas. However, your text is intended for a human reader, so clearer, easier-to-read language is better.

• Use symbols for logic statements.
• Use symbols if it is cumbersome to express your ideas in words.
•  Use words if it is not much longer than using symbols.
• Symbols should be separated by words or punctuation marks.

Choose the best options from the following options.

In mathematical writing, we should not start a sentence with a symbol or a formula.

Choose the sentences that don't make this mistake.

In order to distinguish vectors from scalars, vectors should all be consistently denoted by either using letters with boldface, or by adding either a tilde beneath or an arrow above the symbol. This is especially true when trying to distinguish the scalar zero from a zero vector.

Choose the best options from the following options.

When writing mathematics, make sure that you use the correct notations for superscripts, subscripts and number systems. We use blackboard letters for number systems. In , the command \mathbb will create a blackboard letter, e.g., \mathbb{R} for the set of all real numbers .

Choose the options which you think are the best from the list below. Note that each sentence is trying to express the same information.

It is also possible to go too far and start adding punctuation where punctuation is not needed.  For example, a full stop should only be used to indicate when your sentence has finished.

Choose the options which are correctly punctuated from the choices below [select all that apply].

It is important to note that an equation is not considered as sentence in it's own right. You should treat equations like nouns, and make them part of a sentence.

You can often use linking phrases to make the equation part of a complete sentence.

Keeping this in mind, choose the best answer from the following options.

You should avoid using asterisks (*) and the letter x to denote multiplication in general. When writing down vector equations, the following rules are considered best practice.

• The symbols and are used for the dot (scalar) product and the cross (vector) product.
• You should omit the sign for scalar multiplication of vectors.

Select the options which you think are the best. Here, we assume that and are vectors in .

Every sentence must end with a full stop. This holds even when your sentence ends with a mathematical expression, such as a variable or a formula.

Which of the following is a correctly punctuated sentence?
