the answer is : 4140. set it up the problem. do 2 times 5 then 2 times 4. also carry the one up top and add it. then multiply 2 and 3. you should get 690. to the line underneath you add 0 under the last digit. then you multiply 1 times 5, 1 times 4 and 1 times 3. for that second line you should get 3450. add 690 and 3450 and you should get 4140. i hope this helped
