Memasuki dunia matematika dalam bahasa Inggris sebenarnya cukup menyenangkan karena kosakatanya sangat teratur. Empat operasi dasar yang wajib dikuasai adalah addition (+), subtraction (-), multiplication (×), dan division (÷). Saat menggunakannya dalam kalimat, kamu sering menyebutnya dengan kata kerja seperti plus, minus, times, atau divided by. Menariknya, setiap hasil dari operasi ini memiliki nama keren sendiri seperti sum untuk hasil penjumlahan, difference untuk pengurangan, product untuk perkalian, dan quotient untuk pembagian.
Selain operasi hitung, penting juga untuk mengenal jenis-jenis bilangan dan bentuk dasar dalam geometri agar komunikasi matematis kamu semakin lancar. Kamu akan sering menemui istilah even numbers (bilangan genap) dan odd numbers (bilangan ganjil), serta fractions (pecahan) dan decimals. Di sisi lain, dalam konsep geometri, kamu mulai dari bentuk sederhana seperti square (persegi), circle (lingkaran), hingga triangle (segitiga). Memahami istilah-istilah ini bukan hanya membantu dalam pelajaran formal, tetapi juga sangat berguna dalam aktivitas sehari-hari seperti saat berbelanja atau mengukur sesuatu di rumah.
