Calculati
m+n=?
m=57×6-(81:8×7×0)+3×9+(400-46×8-36:4)
n=123×4+209×2-168×3

Răspuns :

  m+n=57x6-(81:8x7x0)+3x9+(400-46x8-36:4)+123x4+209x2-168x3
=342-0+27+23+492+418-504
=798

intai se calculeaza inmultirile si impartirile in ordinea in care apar,iar apoi adunarile si scaderile in ordinea in care apar, dar intai faci calculul in paranteza aplicand aceleasi reguli.
