help with "add" on stitches

[jobecca]

Hello there - I am new to the knitting chat room - what a wonderful idea! Please help me with my problem - I am knitting a v-neck vest, and am ready to shape the "v". When I knit to the middle of the row to make the start of the "v", it says "add" 3 stitches - Do they mean increase? And do the added stitches go on the left side of the "v" or the right side?
