When we need to solve multiplication problems, we have many methods we could use. Which method we choose depends on our problem, how many digits our numbers have, and the method we are more comfortable with.
Let's look at a video on how to multiply two 2 digit numbers.
Calculate 26 \times 39 by completing an area model.
Firstly, complete the missing values in the area model.
Now add the values you found in part (a) to calculate 26\times 39.
This video looks at using the algorithm to solve a multiplication problem.
Find 7\times 583.
Select and apply efficient mental and written strategies and appropriate digital technologies to solve problems involving all four operations with whole numbers and make estimates for these computations
