1(2) - (4 - 3 - 2/2)
This is basically the equation but this is the full equation.
y − ( 4 − x − y ÷ 2); use x = 3, and y = 2

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
