Inference

For maths we used a strategy called Inference and this strategy is great to use and it's good for reading as well but the inference strategy is something where you use you old knowledge and you new knowledge altogether. Example: Jerry has 27 drawings and gave 3 each to his 8 friends. how many did his friend get. 27, 3, 8 27 isn't important so we got 3 and 8. 3 x 8 = 24.
