We'd have to solve another problem as well: Our calculators would have to hold more types of data than numbers. In theory, it would be great to add buttons to our calculator as soon as we are ready for them, but that would lead to a lot of hardware floating around.

HOW TO MAKE A COMPUTER PROGRAM THAT DOES MATH UPGRADE

You could upgrade to a calculator that does all the operations of arithmetic when you're done exploring with this one. As you solve subtraction problems like '5 - 2', you can still check your answer of 3 with this calculator by confirming the sum '3 + 2 = 5.' Likewise, you can solve multiplication problems by adding numbers repeatedly. There's no need for a subtraction, multiplication or division button to get in your way at this phase. The perfect calculator at that stage of learning might have a few more buttons, like the one in Figure 2. Soon after you master counting, you want to practice writing numbers and adding them.

The more a calculator can do out-of-the-box, the more useful it should theoretically be. If you're doing trigonometry and you need to know 3.14159 / 6, the calculator is there to handle it so you can think about what the answer means. The calculator also helps you save time once you've mastered concepts.

You need to know how to multiply six by seven without using your calculator, but it's good to confirm that your answer of 42 is correct by consulting with your calculator. Build your own calculatorĬalculators are prevalent in math classes because they are useful to check your work. Even better, if you write your mathematical statements in code, you'll have the computer to help check your work. If you apply the same care when you're writing down mathematical statements, you'll catch your mistakes faster. The ideas that your statements represent need to make sense to be valid. When you're writing code, it's not enough to write statements with correct syntax. In fact, it's possible that only one of the products is even possible, or that neither product is possible. If instead A and B are matrices, then the products A x B and B x A are usually different. But this is not necessarily the case if A and B are not numbers. For instance, if the letters A and B represent numbers then A x B = B x A. Because these are different instances of the A class, they are not considered equal.īe on the lookout for new mathematical objects that look like ones you know but don't behave the same way. You might expect two identical expressions to be equal, but that's evidently not a rule in Python. If you define a new Python class and create two identical instances of it, they are not equal. This may seem pedantic, but you need to know it to write a correct program.Īnother example which trips up novice programmers (and experienced ones as well) is reference equality. On the other hand, you can't bind a symbol to the literal value 5. The Python statement x = 5 is an instruction to bind the value 5 to the symbol x. But that's not exactly what either of these means, and in fact only the first one is correct. I could read either of these to mean that the symbol x has a value of 5. To a non-programmer, these two lines of Python seem to say the same thing: x = 5 One simple example is variable assignment. In some languages, even forgetting a semicolon at the end of an otherwise correct statement will prevent the program from running.

But any syntactic error or misspelled identifier will cause your program to fail. If your spelling or grammar is slightly off when writing an email, the recipient will probably still know what you are talking about.

One of the first hard lessons you learn in programming is that you can't write your code like you write simple English. These will remind you of the skills you already have that you can lean on in your math studies. There are several specific ideas that translate directly from programming to math. I believe the best way to learn math is with the help of a high-level programming language, and I predict that in the not-so-distant future this will be the norm in math classrooms. Fortunately, if you can already write code, you've already trained your analytical thinking skills and mathematical ideas should come naturally.
