Answer:
105
Step-by-step explanation:
35 x 3
Use the column method, that may help.
Set out like this:
35
3
You start with the right (5 x 3 = 15), carry the 1 to the left and put the 3 under the right column. And then you do 3 x 3 which is 9 but don't forget to ADD the 1 which is 10.
This means the answer is 105
