 The memory profile setting specifies the memory usage for each frontend and backend replica and interacts with the cardinality settings. You can calculate the total memory usage using the formula: 
 
-<!-- M_total = R_fe * M_fe + (P_be * RF_be) * M_be * W_be. -->
-
-$M_{\text{total}} = R_{\text{fe}} \cdot M_{\text{fe}} + (P_{\text{be}} \cdot RF_{\text{be}}) \cdot M_{\text{be}} \cdot W_{\text{be}}$
+*M_total = R_fe * M_fe + (P_be * RF_be) * M_be * W_be*
 
 Where:
 
 | Variable | Description |
 |----------|-------------|
-| $M_{\text{total}}$ | Total memory usage |
-| $R_{\text{fe}}$ | The number of frontend replicas |
-| $M_{\text{fe}}$ | The memory usage of each frontend replica |
-| $P_{\text{be}}$ | The number of backend partitions |
-| $RF_{\text{be}}$ | Backend redundancy factor |
-| $M_{\text{be}}$ | The memory usage of each backend replica |
-| $W_{\text{be}}$ | The number of workers per backend replica |
+| *M_total* | Total memory usage |
+| *R_fe* | The number of frontend replicas |
+| *M_fe*| The memory usage of each frontend replica |
+| *P_be*| The number of backend partitions |

 For example if you choose the *Medium* memory profile, the profile has a frontend memory usage of 1.9 GB and backend memory usage of 1.5 GB. Assume that the broker configuration is 2 frontend replicas, 2 backend partitions, and a backend redundancy factor of 2. The total memory usage is:
