'cover up' method

it seems helpful to begin work on solving equations informally - just by thinking about them



















equations involving trickier 'take away from' and 'divide into' operations, lend themselves to being solved by staging or simplifying a given equation - sometimes called the 'cover up' method

some students prefer this technique to one involving inverse operations
maybe unfortunately
