Bạn thêm những từ này vào giữa 2 số nhé
(+) and, make, plus
(-) minus [hoặc from (nhưng nói ngược)]
(x) multiplied by hoặc times
(÷) divided by [hoặc into (nhưng nói ngược)]
Về kết quả thì bạn sử dụng is/are hoặc equals nha
vd: 1+1=2
One plus one equals two
One plus one is two
One plus one are two
2-1=1
Two minus one equals/is/are one
One from two ........................... (đối với from chỉ cần đổi chỗ 2 số đó là được rồi)
Tương tự nhé!!!
Cái câu two minus one equals/is/are one
Các từ is/are one là thay cho từ nào đấy bn?
