 The scale factor is also a setting that you can configure in an operating system. Here's the formula for calculating the TCP window size by using scale factors:
 
-`TCP window size = TCP window size in bytes \* (2^scale factor)`
+`TCP window size = TCP window size in bytes * (2^scale factor)`
 
 Here's the calculation for a window scale factor of 3 and a window size of 65,535:
 
-`65,535 \* (2^3) = 262,140 bytes`
+`65,535 * (2^3) = 262,140 bytes`
 
 A scale factor of 14 results in a TCP window size of 14 (the maximum offset allowed). The TCP window size will be 1,073,725,440 bytes (8.5 gigabits).
