Remember, a complex number is very similar to a binomial. We’re dealing with imaginary and real numbers at the same time. We already took a look at addition and subtraction, so let’s move on to multiplication and division. These are a little trickier, but only division involves a skill you may not have used yet. […]

Here are some tips to help you get the most out of your calculator on test day. You can use a calculator on the ACT Math Test. You cannot use a calculator on the Science Test. (Or the English and Reading Tests… not that you’d want to.) Make sure the calculator you want to use […]

Complex Numbers Complex numbers are kind of like binomials. They have two parts: a real number and an imaginary number. Some examples of complex numbers would be (3 + 4i) , (-2, -i), or (7 – 3i). Make sense? We’ve got the real and the imaginary working together in peace and harmony. Let’s talk about what […]
