## What is reduce system?

A system in which words (expressions) of a formal language can be transformed according to a finite set of rewrite rules is called a reduction system. While reduction systems are also known as string rewriting systems or term rewriting systems, the term “reduction system” is more general.

**What is a CAS math?**

A computer algebra system (CAS) or symbolic algebra system (SAS) is any mathematical software with the ability to manipulate mathematical expressions in a way similar to the traditional manual computations of mathematicians and scientists.

### How do you reduce reuse recycle?

Here are some ideas:

- Refill a water bottle with water from home instead of buying a new one.
- Update your computer rather than throwing it out and getting a replacement.
- Ditch plastic bags and choose reusable, environmentally-friendly bags instead.

**How do you simplify numbers?**

Some ways to simplify a number…

- Round it off. Create zeros. So 199 becomes 200.
- Round to an order of magnitude. Round a lot, to the nearest “power of ten”.
- Slide the decimal point. Compact those zeros created by rounding.
- Substitute a number you can remember. Instead of rounding, find a nearby number you can remember.

#### What are the 3 R’s of waste management?

The principle of reducing waste, reusing and recycling resources and products is often called the “3Rs.” Reducing means choosing to use things with care to reduce the amount of waste generated.

**What is reduce example?**

To reduce is to make something smaller or to become or feel smaller, or forcing someone into a less desirable position. When you sell off half of your doll collection, your actions are an example of reduce. An example of reduce is when your stomach gets smaller because you are on a diet; your stomach reduces.

## What kind of computer algebra system is reduce?

REDUCE is a portable general-purpose computer algebra system. It is a system for doing scalar, vector and matrix algebra by computer, which also supports arbitrary precision numerical approximation and interfaces to gnuplot to provide graphics.

**How do I install reduce on my computer?**

Download the recommended file to your computer and install REDUCE in the normal way: on Windows, double-click on the installer file to execute it; on MacOS, double-click on the installer file to open it and then drag the REDUCE icon to your Applications folder.

### Who is the creator of the reduce system?

REDUCE is an interactive system for general algebraic computations of interest to mathematicians, scientists and engineers. It can be used interactively for simple calculations but also provides a flexible and expressive user programming language. The development of the REDUCE computer algebra system was started in the 1960s by Anthony C. Hearn.

**Is the reduce software available free of charge?**

REDUCE (and its complete source code) is available free of charge for most common computing systems, in some cases in more than one version for the same machine. The manual and other support documents and tutorials are also included in the distributions.
