Fraction Solver is a no-nonsense easy-to-use application available on the Apple iTunes Store. Use Fraction Solver
to perform calculations on fractions. With the free-form data entry you enter your fractional expression as a true fraction, that is,
using a numerator-slash-denominator format. It supports algebraic hierarchy and parentheses. The results are displayed in several forms: the raw fraction
result,a reduced result, a mixed result, and a decimal equivalent. Additionally the lists of factors and prime factorization are displayed with the common
factor highlighted in red.

This is what you would see when calculating

**2/5 + 3/12**:

**How To Use Fraction Solver**
Using the three rows of buttons in the upper portion of the screen, enter an expression of fractions and finish by touching the "=" button.
Your results will be displayed in the lower portion of the screen. These results will extend off the bottom of the screen; flick the display upward
to see all of your results.

These are the details of all of the buttons:

**The Top Row**

These are the digits 0 - 9. Touch any of them to enter digits into your fraction expression.

**The Middle Row**
These are all mathematical operators for your fraction expression:

**_ (Underscore)**
Use the underscore to separate the whole number portion of a mixed fraction from the fractional portion. For example, to enter the mixed fraction
one and two thirds, enter

**1_2/3**.

**/ (Backslash)**
Use the backslash to separate the numerator and the denominator of a fraction. For example, three-fourths would be entered as

**3/4**.

**+ (Addition)**
Use

**+** as the addition operator. To add 1/2 and 3/4, enter

**1/2+3/4**. If you touch the "=" button you will see
a list of results based on the sum of 5/4.

**- (Subtraction)**
Use

**-** as the subtraction operator. To subtract 1/2 from 3/4, enter

**3/4-1/2**. If you touch the "=" button you will see
a list of results based on the difference of 1/4.

*** or x (Multiplication)**
Use either

***** or

**x** as the multiplication operator. To multiply 1/2 and 3/4, enter

**1/2*3/4** or

**1/2x3/4**. If you touch the "=" button you will see
a list of results based on the product of 3/8.

**÷ (Division)**
Use

**÷** as the division operator. To divide 3/4 and 1/2, enter

**3/4÷1/2**. If you touch the "=" button you will see
a list of results based on the quotient of 6/4. Remember that the backslash (/) separates a numerator and denominator; it is not a
division operator. The expression 3/4 / 1/2 will not yield anything useful.

**( ) (Parentheses)**
Use

**( )** to force the order of operations. Fraction Solver uses standard algebraic hierarchy. You can force the order to suit your entry.
Note the difference between

**1/4 + 1/3 * 1/2** and

**(1/4 + 1/3) * 1/2**. Without the parentheses, the

**1/3 * 1/2** was evaluated first since according to
algebraic hierarchy, multiplications and divisions are performed first; the additions and subtractions follow. Using the parentheses forced the

**1/4 + 1/3** portion to evaluate first.

**= (Equals)**
Use

**=** to evaluate your calculation.

**The Bottom Row**
**C**
Completely clear the expression.

**Space**
Add space to the expression. The space does nothing mathematically but it can make the expression easier to read.

**|<**
Move the cursor to the beginning of the expression.

**<**
Move the cursor one character to the left.

**>**
Move the cursor one character to the right.

**>|**
Move the cursor to the end of the expression.

**Del**
Clear the character to the left of the cursor (|).

**?**
Switch to the help screen.

**Other Considerations**

Fraction Solver does its work using integer math. Because of this, there are some situations that might at first seem like an error
occurred, but upon examination, are correct.

**1.** When doing a division, Fraction Solver will cross-multiply rather than divide. It will use these results without any preliminary reduction in
its display of the raw result. For example, if you divide 10/21 by 2/7, you might expect the raw result to be 5/3 since dividing the numerators
yields 5 (10 divided by 2) and dividing the denominators yields 3 (21 divided by 7). Instead, the raw result will be 70/42, since 10 multiplied by
7 yields 70 and 21 multiplied by 2 yields 42. 70/42 reduces to 5/3, but it may not have been readily apparent that Fraction Solver cross-multiplied
rather than dividing numerators and denominators.

**2.** When using parentheses to enclose a division in a denominator, Fraction Solver will consider the fractional equivalent and cross-multiply rather
than divide. For example, if you entered 1/(6÷3), you might expect an immediate raw result of 1/2. Rather, Fraction Solver will consider this
operation as 1/6 x 3/1 to yield a result of 3/6. Again, 3/6 reduced is 1/2, but it may not be readily apparent how Fraction Solver arrived at the
preliminary result of 3/6.

**Hint**

To get information about a fraction such as its reduced form or the common factors without actually performing a calculation, simply enter the fraction
and touch the

**"="** button. For example, to reduce 10/12 enter

**"1 0 / 1 2 =".**
