Hi,
One option is to solve it like this:
7(499)= 7(400) + 7(90) + 7(9) = 2800 + 630 + 63 = 3493
Or,
7(499)= 7(500) - 7(1) = 3500 - 7 = 3493
Hope this helps! If my answer was not clear enough or you’d like further explanation please let me know. Also, English is not my first language, so I’m sorry for any mistakes.
