Pembahasan :
Operasi hitung campuran adalah penghitungan di mana terdapat dua tanda penghitungan yang berbeda dalam satu soal.
Operasi hitung campuran dibagi menjadi 4 yaitu :
1️⃣ Perkalian
Perkalian adalah salah satu dari empat dasar operasi matematika dari aritmetika, dengan yang lainnya adalah penambahan, pengurangan dan pembagian. Hasil dari operasi perkalian disebut darab.
2️⃣ Pembagian
Pembagian adalah operasi aritmetika dasar yang merupakan kebalikan dari operasi perkalian. Operasi pembagian ini dinotasikan dengan tanda (÷) (division) atau / (slash).
3️⃣ Penjumlahan
Penambahan adalah salah satu dari empat operasi aritmetika dasar. Penjumlahan merupakan penambahan sekelompok bilangan atau lebih menjadi suatu bilangan yang disebut jumlah.
4️⃣ Pengurangan
Pengurangan adalah operasi aritmetika yang mewakili operasi menghapus objek dari koleksi. Pengurangan ditandai dengan tanda minus ( - )
Aturan-aturan operasi hitung campuran yaitu :
➡️ Operasi yang berada dalam kurung dikerjakan lebih dahulu.
➡️ Dahulukan bilangan berpangkat.
➡️ Dahulukan perkalian dan pembagian sebelum penjumlahan dan pengurangan.
➡️ Jika ada perkalian dan pembagian tanpa tanda kurung, kerjakan berurutan dari kiri ke kanan.
Langkah-langkah dalam menghitung operasi hitung campuran yaitu :
✔️Operasi penjumlahan dan pengurangan sama kuat.
✔️ Operasi perkalian dan pembagian sama kuat.
✔️ Operasi perkalian dan pembagian lebih kuat dibandingkan operasi penjumlahan atau pengurangan.
