Urutan Operasi Perhitungan

Urutan operasi perhitungan adalah:

  1. Operasi yang berada di dalam kurung.
  2. Perhitungan pangkat.
  3. Perkalian dan pembagian dari kiri ke kanan.
  4. Terakhir, penambahan dan pengurangan dari kiri ke kanan.

Berikut beberapa contohnya.

\displaystyle \begin{array}{l}{{\left( 3+1 \right)}^{2}}\times 2={{4}^{2}}\times 2\\=16\times 2\\=32\end{array}

\displaystyle \begin{array}{l}3+{{1}^{2}}\times 2=3+1\times 2\\=3+2\\=5\end{array}
