If Jordan ate J almonds. Half of this is J/2. 3 more than this is J/2+3=25.
So J/2=22, J=44. Jordan ate 44 almonds.
Another way to solve this is to work backwards.
25 is 3 more than half the almonds Jordan ate.
25-3=22 is half the almonds Jordan ate. (Subtract is the opposite from add)
Jordan ate twice as many almonds as this, so 2×22=44 almonds. (Double is the opposite from half)
