When asked to solve a quadratic equation, we are really finding the roots – where the parabola cuts the x-axis, therefore when we have the graph drawn, it is very easy to do this. Looking at the graph ...

For example, the simultaneous equations \(3a + 2b = 17\) and \(4a - b = 30\) have no common coefficient as the coefficients of \(a\) are 3 and 4, and the coefficients of \(b\) are 2 and -1. Remember ...

I’ve been out of school a long time (I mean a long time), yet I think I’m still pretty good at basic math. I’m always able to figure out whether a “bargain buy” at the supermarket is actually a ...

She’s right—using simultaneous equations does get really complicated, and if you’d like to send me your work for the solution, I’d love to see it. But the system is also kind of a trick. Like a sudoku ...

Walking on to the deck, you see a whiteboard with numbers and symbols scribbled all over. The novice swimmer might ask, “Am I in math class or at swim practice?” However, the experienced swimmer knows ...
