 The stochastic process $$M_t$$ above is a **submartingale**
 if the current value is a lower bound for the expectation:
 
-3.  For $$0 \le s \le t$$, the conditional expectation $$\mathbf{E}(M_t | \mathcal{F}_s) \ge M_s$$.
+3.  For $$0 \le s \le t$$, the conditional expectation
+    $$\mathbf{E}(M_t | \mathcal{F}_s) \ge M_s$$.
 
 Analogouly, $$M_t$$ is a **supermartingale**
 if the current value is an upper bound instead:
 
-3.  For $$0 \le s \le t$$, the conditional expectation $$\mathbf{E}(M_t | \mathcal{F}_s) \le M_s$$.
+3.  For $$0 \le s \le t$$, the conditional expectation
+    $$\mathbf{E}(M_t | \mathcal{F}_s) \le M_s$$.
 
 Clearly, submartingales and supermartingales are *biased* random walks,
 since they will tend to increase and decrease with time, respectively.
