Two numbers, one question

Challenge 7 of 12

Both sides of a question can be boxes. The orange bar is cats and the blue one is dogs, so the question is really asking which bar is longer.

Set dogs to a number that makes the answer true.

Lesson Bigger or Smaller

Everything you have written so far has been an instruction: draw this, add that, do it again. This topic is about something different — a question.

score > 100

That is a question. It is asking whether the number in score is bigger than 100, and like any question it has an answer. The answer is one of only two things: true, or false. There is no third possibility and no in between.

You can see the answer, because write can draw it just as happily as it draws words and numbers:

write(score > 100, 130, 300);

If score holds 240 the canvas says true. If score holds 60 it says false. Nothing else in the sketch changes — only the word.

There are two signs to know for now:

score > 100 asks whether score is bigger
score < 100 asks whether score is smaller

The wide end of the sign always faces the bigger side, which is a fair way to remember it.

Both sides of a question can be boxes, and either side can be a sum worked out first:

cats > dogs
apples + pears > 300

In these challenges every number is drawn as a bar as long as it is big, so you can see the question as well as read it. Turn the grid on if you want to measure a bar; the numbers along the top are the same numbers you are typing.

One thing to be clear about before the next topic. A question does not do anything. It has an answer and that is all. What happens next — a colour changing, a shape appearing — is the next topic's job, and it is called if.
