Add the term after the plus sign to the term or group before it.

The passage around this formula

Dreamer-style world models learn a compact latent-dynamics model — a recurrent state-space model that predicts both a stochastic and a deterministic component of future latent state — and then train a policy by backpropagating through imagined rollouts inside that latent space, rather than through real or simulated environment steps directly [ 8 ] . DayDreamer took that specific mechanism, previously demonstrated mostly in video-game and simulated benchmarks, and applied it to physical robots learning online, without a simulator and without human demonstrations, reporting that four different physical robots (a quadruped and several manipulator arms) learned locomotion and manipulation skills…

Addition combines quantities; subtraction measures the signed difference between them. Parentheses show what is combined before the rest of the expression is evaluated.
