Confused Learner

Hello All

I hope this message finds you all in good health and spirits. Its my first post on the forums, My names Vika, Im from South Africa very keen on improving and bettering my understanding and knowledge on trading as well and formulating my own trading strategy at some point as just wandering on the Forex market can be like walking on the Highway you bound to get hit by a number of cars and so has my journey but still very keen someone said “Its not a loss if you learn from it”

To my question i have been going through you education course and under (What is Equity) lesson 30 Pre-School there is a calculation at
Example: Account Equity When an Existing Trade is Winning : how is the total $1200 but the calculation is $1000+100.

Thank you for your time
