-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.

3 the answer is 3!

what is +49 -(-24)

To solve the expression +49 - (-24), we can simplify it by following the order of operations (BEDMAS).

Starting with the subtraction inside the parentheses, we have -(-24). To simplify this, we can think of it as a double negation which cancels out the negative sign. So, -(-24) becomes +24.

Now we have +49 + 24. We can simply add the two numbers together to get the final answer:

+49 + 24 = 73

Therefore, +49 - (-24) is equal to 73.
