369 + 488 = 857605 - 352 = 253
Now, substituting these values back into the original equation:
857 - 687 + 253 = 423
Therefore, (369 + 488) - 687 + (605 - 352) = 423.
369 + 488 = 857
605 - 352 = 253
Now, substituting these values back into the original equation:
857 - 687 + 253 = 423
Therefore, (369 + 488) - 687 + (605 - 352) = 423.
