Answer:

In a problem you always start with Multiplication instead of subtraction

Step-by-step explanation:

You can remember this by PEMDAS

parenthesis always come first

Exponents come second

Multiplication and Division whichever is more to the left so 7 times 2 divided by 3; you would do the multiplication first

Addition and subtraction has the same Multiplication and Division whichever shows up first.

Answer:

multiplication.

Step-by-step explanation:

A good way to remember the order of operations is Please Excuse My Dear Aunt Sally, or PEMDAS. PEMDAS stands for Parentheses, Exponents, Multiplication/Division, Addition/Subtraction. If multiplication and division are in the same problem, you go in order. Same with addition in subtraction. What that means in this example is that since in PEMDAS, the M is first, you would multiply first instead of subtracting. :)

Who started the problem correctly? The problem form is (-5) - (-1 3/4).
Veronika [31]

Answer:

Shane started the problem correctly

Step-by-step explanation:

We are given problem (-5) - (-1 3/4).

Mariah started the problem as (-5) + 1 - 3/4

Shane started the problem as (-5) + 1 + 3/4

We need to find who started the problem correctly.

The problem should be started by converting the mixed fraction into improper fraction i,e

-5-(-1\frac{3}{4})\\=-5-(-1-\frac{3}{4} )\\=-5-(-\frac{7}{4})

Now we will solve bracket by multiplying -1 with term inside the bracket i.e

=-5+\frac{7}{4}

= \frac{-13}{4}

Let's compare both the procedures now:

Mariah:

(-5) + 1 - \frac{3}{4}

=(-5) - \frac{1}{4}

=\frac{-21}{4}

Therefore, Mariah did not start the problem correctly.

Shane:

(-5) + 1 + \frac{3}{4}

= -5 + \frac{7}{4}

= \frac{-13}{4}

Therefore, Shane started the problem correctly.
