    What follows is the Richtmyer two-step Lax–Wendroff method. The first step in the Richtmyer two-step Lax–Wendroff method calculates values for f(u(x, t)) at half time steps, t n + 1/2 and half grid points, x i + 1/2. In the second step values at t n + 1 are calculated using the data for t n and t n + 1/2.

    Step 4 is where the units digit to step 3’s initial answer to: (u 1 • u 2) is attached (symbolized by: @) to the end of the sum of steps 1-3. Step 4 = D @ u (u 1 • u 2) = E. Finally this number is taken and the following is added to it: Step 5 = E + (T 1 • T 2) = Final Answer. For example, in the following problem: 79 • 26, by ...
