What is a cryptogram?

Short Answer

Expert verified
A Cryptogram is a puzzle that consists of a short piece of encrypted text with a substitution cipher. To solve it, figure out which alphabet character replaces which.

Step by step solution

01

Understanding the problem

First, the task is to understand what a Cryptogram is. A Cryptogram is a sentence or paragraph where each character is replaced by a different character.
02

Understanding the encoded message

Next, the message is encrypted using a substitution cipher where each letter in the plain text is replaced by another to give a code. The key to solving the Cryptogram is understanding the substitution.
03

Decoding the cryptogram

To decode the cryptogram, the correct replacements have to be found for each character in the encoded message.

If \(I\) is the multiplicative identity matrix of onder \(2,\) find \((I-A)^{-1}\) for the given matrix \(A\) $$\left[\begin{array}{rr}8 & -5 \\\\-3 & 2\end{array}\right]$$

Use a coding matrix \(A\) of your choice. Use a graphing utility to find the multiplicative inverse of your coding matrix. Write a cryptogram for cach message. Check your result by decoding the cryptogram. Use your graphing utility to perform all necessary matrix multiplications. $$\begin{array}{llllllllllll}\mathrm{A} & \mathrm{R} & \mathrm{T} & \- & \mathrm{E} & \mathrm{N} & \mathrm{R} & \mathrm{I} & \mathrm{C} & \mathrm{H} & \mathrm{E} & \mathrm{S} \\\1 & 18 & 20 & 0 & 5 & 14 & 18 & 9 & 3 & 8 & 5 & 19\end{array}$$

When expanding a determinant by minors, when is it necessary to supply minus signs?

Determine whether each statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement. Two \(2 \times 2\) invertible matrices can have a matrix sum that is not invertible.
