    Perform the idicated operations. Write fractional answers as mixed numbers or as proper fractions reduced to lowest terms.

    One:
    -3-(-4)-|4-7|

    Two:

    0.096492 ( Divid) 1.72

    Simplify:

    3(1-5)-[(1-7)(-5)]


    -(-{-[-(-64)]})


    -|-3+4|+5-7



    Evaluate:
    c-bc if b=-1 and c= -2

    What seems to be the problem, what do you need help with? Remember that you need to show what you've done on the problems; solutions are not just handed out.

    You need to show us what you have done so far. We don't just give answers since that we be a violation of the PF Guidelines you agreed with when signing up to this forum.

    Let me give you a hint : do you know the "order of execution" of the different mathematical operations ? Like, for example, multiplication has a priority over addition or subtraction...

    and

    -*-= +
    -*+ = -
    +*- = -
    +*+ = +

    So -(-4) = (-1)*(-1)*4 = 4

    I will solve this one to show you :

    -(-4) = +4

    -3+4-|-3| = -3+4-3 sine |-3| = 3

    Thus : -6 + 4 = -2
