Write the elements of the set: the letters of the word “Drift.”

If we look at this question for the first time, we might say to ourselves, what is this got to do with maths? There are no numbers in it. There are no mentions of shapes or angles. But if we look carefully, we can see that the question is asking us about a set. In maths, a set is a collection of different objects or elements. And we write those elements usually inside braces like these. This particular problem doesn’t ask us to draw the braces. It just asked us to write what’s inside, to write the elements of the set. A set might show all the whole numbers between one and six or maybe all the operations we use when calculating.

Notice that we separate each element of the set by using a comma. In this particular problem, we are asked to write the elements of the set, the letters of the word “Drift.” There are five letters in the word drift. And if they’re each a separate element of a set, we need to separate them using commas. 𝐷, let’s make that a capital 𝐷 because it is a capital 𝐷 in the word that we’re shown, 𝑟, 𝑖, 𝑓, and also 𝑡. And we’ll erase the braces because we’re not asked to show those in the question. There are five letters in the word drift. And if we use them to form the elements of a set. Our set will contain the same five letters, 𝐷, 𝑟, 𝑖, 𝑓, and 𝑡.
