technically this is not an equaiton since it doesn't have an equals sign, it would be more like an expression, but anyways
remember order of operations
parenthasees
multiply and divide
add and subtract
4+(-3)-2*(-6)
multiply
-2*(-6)=12 (remember multiplying 2 negatives make a positive)
now we has
3+(-2)+12
add
3+(-2)=3-2=1
now we have
1+12
13
result is 13
