(+7)+(+4)=. this isn't in standard form yet. You have 4 and 7, in standard form you have to remove the and which is the plus sign and the parenthesis. It looks like this now +7 +4.
Other examples of standard forms in integer are: -9 +6 and -2 -2
Adding Integer Column 2:
1.) -2 +3 (standard form)= +1
2.) -4 -3 (standard form)= -7
3.) -2 +7 (standard form)= +5
I liked how clear your pictures were! Next time think you should put a video and a link to make it bettter.
