2$=2$Work it out

Work out $-2+(-5)$.

1$+\,-$ becomes $-$: $-2-5$Rewrite the double sign ($+\,-\to-$, $-\,-\to+$)

2Work it out

Check - Starting at $-2$ and going $5$ MORE negative gives...

A $3$B $-7$C $7$D $-3$

Work out $-8-(-3)$.

1Rewrite the double sign ($+\,-\to-$, $-\,-\to+$)

2Work it out

Check - From $-8$, adding $3$ moves you which way?

A left (more negative)B right (towards zero), to $-5$C nowhereD to $-11$
