00:07 Let's start solving the math problem.
00:10 First, remember the correct order of operations.
00:14 Begin by calculating everything inside the parentheses.
00:24 Next, turn division into fractions for easier processing.
00:37 A negative divided by a negative equals a positive.
00:43 Now, break down forty-nine into factors, seven and seven. Then reduce if possible.
00:58 Change division to multiplication by using the reciprocal.
01:02 Switch the numerator and denominator.
01:07 Multiply the numerators together and the denominators together.
01:18 And that's how we find the solution to this problem.

Step-by-step solution

First, let's solve what's inside the parentheses:

3+2=1 -3+2=-1

Now the exercise looks like this:

7:49:+14:1= -7:-49:+14:-1=

Let's treat the exercise as division between two simple fractions:

(7:49):(+14:1)= (-7:-49):(+14:-1)=

749:+141= \frac{-7}{-49}:\frac{+14}{-1}=

Let's look at the simple fraction on the left side.

Since we are dividing a negative number by a negative number, the result will be positive.

Let's break down 49 into a multiplication exercise:

77×7= \frac{7}{7\times7}=

Let's reduce the 7 in the numerator and denominator and we get:

17 \frac{1}{7}

Now the exercise we got is:

17:+141= \frac{1}{7}:\frac{+14}{-1}=

Let's convert the division to multiplication, don't forget to switch between numerator and denominator:

17×1+14= \frac{1}{7}\times\frac{-1}{+14}=

Let's reduce to one exercise:

1×17×14=1+98 \frac{1\times-1}{7\times14}=\frac{-1}{+98}

Since we are dividing a negative number by a positive number, the result will be negative:

:+= -:+=-

Therefore we get:

198 -\frac{1}{98}

Final Answer

198 -\frac{1}{98}
