Answer the practice questions using your white board and marker.
9. Backtracking
You will be able to backtrack number sentences to calculate an unknown quantity.
What is Backtracking?
When you change a number by adding +, subtracting -, multiplying x or dividing / you can undo the changes by performing the INVERSE (opposite) of each operation.
Addition is the inverse of subtraction (+ undoes -)
Subtraction is the inverse of addition (- undoes +)
Multiplication is the inverse of division (x undoes /)
Division is the inverse of multiplication (/ undoes x)
Undoing the change is called BACKTRACKING.
The easiest way to backtrack is to write the equation backwards using the INVERSE +, -, x & / signs.
(? + 10) / 2 = 7 becomes (7 x 2) – 10 =
(? x 3) – 4 = 11 becomes (11 + 4) / 3 =
Use backtracking to rewrite these equations, then work out the unknown:-
