• i feel so dumb sometimes i cant add and subtract in my head >.<
• It's okay, all you need is practice. Practice, pracTICE, PRACTICE
• It depends on how you like it to be. I like to go from right to left.
• What are minuend and subtrahend?
Subtrahend is the number take from the minuend.
So in "3 - 2 = 1", 3 is the minuend and 2 is the subtrahend.
• 10.1-3.93 is so easy but a little bit hard
• Note that 3.93 is only 0.07 less than 4. So we can subtract 4 from 10.1 to get 6.1 (or 6.10), then add back 0.07 to get a final answer of 6.17.

Have a blessed, wonderful day!
• I'm pretty sure subtracting from left to right isn't right? I think most ppl got taught subtracting from right to left. Because if you subtract from left to right you will have to go back and carry the numbers you've already subtracted and resubtract THAT number because the number will have changed and it gets quite messed up.
