Four Rules

Next week’s maths class is all about the four rules of arithmetic, the fundamental operations of plus, minus, times and divide, which most maths then depends on, and before putting the final touches to the workbook this evening, I was using all four throughout the day, first in compiling my four pay claims, adding up the hours and multiplying by the various hourly rates, and then in ordering a “take-away” (Chinese) and dividing it up between the three of us for tea.
