-4+[3-10]
Just use BEDMAS...bracket, exponent, division and multiplication, addition and subtraction.
-4+[3-10]
Since 3-10 is in the brackets, you do that first and get -4, so you have -4 + (-4), and your final answer is -8.
Raj must have made a typo.
3-10 = -7, giving you a -11 as a final answer.
I hope this helps a little more. Thanks for asking.
