echo "3 2 + 10 * p" | dc<\/code><\/pre>\nHere, the relationship between 3 and 2 is addition. The addition sign is placed after the numbers are given. After the addition operator adds the top two elements of the stack (3 and 2), 10 is pushed onto the stack.<\/p>\n
Then the multiplication operator *<\/code> multiplies 5<\/strong> and 10<\/strong> and pushes the result (50)<\/strong> back onto the stack.![\"dc](\"https:\/\/linuxsimply.com\/wp-content\/uploads\/2023\/11\/8.-dc-command-for-math-in-Bash.png\")
<\/p>\n<\/span>7. \u201cawk\u201d Command<\/span><\/h3>\nThe awk <\/strong>command is a text-processing utility that also supports mathematical calculations. It can handle floating point arithmetic. One can write the expression to be evaluated within the BEGIN<\/strong> block or use the printf <\/strong>command. Let\u2019s evaluate the expression 10 * (3 + 2) <\/strong>using the awk:<\/p>\necho "10 3 2" | awk '{printf "%.0f\\n", $1 ^ ($2 + $3)}'<\/code><\/pre>\nHere,the echo <\/strong>command is used to pass the numbers involved in the calculation. Then these numbers are piped to the awk<\/strong> command. The awk<\/strong> command reads the numbers using the $1<\/code>,
