Information systems. Polymathlove.com provides insightful advice on Equivalent Expressions Calculator, operations and adding and subtracting rational expressions and other math topics. Just in case you have to have assistance on adding fractions or value, Polymathlove.com is the ideal site to pay a visit to! Starting with the first number ‘1’, we move ahead in the way given below: 1 x 2 + 1 = 3 3 x 2 + 1 = 7 7 x 2 + 1 = 15 15 x 2 + 1 = 31 31 x 2 + 1 = 63 63 x 2 + 1 = 127 Therefore 127 is the next number in the series.

- Expressions 1.3.1 MAC OS X Expressions 1.3.1 Size: 5.30 MB It lets you play with regular. Just type your pattern and some text to test it. All the changes are updated while you’re typing text or pattern. App highlights the syntax, so the pattern is easy-to-read and modify.
- For example, 2(3 + 8) is a numeric expression. Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression. Simplify the algebraic expression: Then evaluate the simplified expression for x = 3 and y = -2.
Type in your sum to see how to solve it step by step. Examples: 2+3*4 or 3/4*3

You will see what the calculator thinks you entered (which may be a little different to what you typed), and then a step-by-step solution.
Note: there can be more than one way to find a solution.
The calculator is still under development and may get things wrong, so be careful!
Tree View
Press the 'tree' button to see your sum as a tree. You would do the calculations from the top down .. sometimes you have a choice which calculation to do first.
