N'akwụkwọ a, anyị ga-atụle iwu ndị bụ isi maka imeghe brackets, na-esonyere ha na ihe atụ maka nghọta ka mma nke ihe ọmụmụ.
Mgbasa nke mgbodo - nnọchi nke okwu nwere brackets na okwu nhata ya, mana enweghị braket.
Iwu mgbasawanye braket
Iwu 1
Ọ bụrụ na enwere "gbakwunyere" n'ihu brackets, mgbe ahụ, akara ngosi nke nọmba niile dị n'ime brackets na-agbanwe agbanwe.
Nkọwa: Ndị ahụ. Plus times gbakwunyere na-eme gbakwunyere, na gbakwunyere ugboro mwepu na-eme mwepu.
atụ:
6 + (21 - 18 - 37) =6 + 21 – 18 – 37 20 + (-8 + 42 – 86 – 97) =20 – 8 + 42 – 86 – 97
Iwu 2
Ọ bụrụ na enwere mwepu n'ihu brackets, mgbe ahụ, a na-atụgharị akara ngosi nke nọmba niile n'ime brackets.
Nkọwa: Ndị ahụ. Oge mwepu a gbakwunyere bụ mwepu, na mwepu oge a mwepu bụ gbakwunyere.
atụ:
65 – (-20 + 16 – 3) =65 + 20 - 16 + 3 116 – (49 + 37 – 18 – 21) =116 – 49 – 37 + 18 + 21

Ọ bụrụ na enwere akara “mmụbawanye” n'ihu ma ọ bụ mgbe brackets gasịrị, ọ dabere na omume a na-eme n'ime ha:
Mgbakwunye na/ma ọ bụ mwepu
a ⋅ (b - c + d) =a ⋅ b - a ⋅ c + a ⋅ d (b + c – d) ⋅ a =a ⋅ b + a ⋅ c - a ⋅ d
Ntinyeghari
a ⋅ (b⋅ c⋅ d) =a ⋅ b⋅ c⋅ d (b ⋅ c ⋅ d) ⋅ a =b ⋅ с ⋅ d ⋅ a
Division
a ⋅ (b : c) =(a ⋅ b): p =(a: c) ⋅ b (a : b) c =(a ⋅ c): b =(c : b) ⋅ a
atụ:
18 ⋅ (11 + 5 - 3) =18 ⋅ 11 + 18 ⋅ 5 - 18 ⋅ 3 4 ⋅ (9 ⋅ 13 ⋅ 27) =4 ⋅ 9⋅ 13⋅ 27 100 ⋅ (36:12) =(100 ⋅ 36): 12

Ọ bụrụ na enwere akara nkewa n'ihu ma ọ bụ mgbe brackets gasịrị, mgbe ahụ, dị ka iwu dị n'elu, ọ dabere na ihe omume a na-eme n'ime ha:
Mgbakwunye na/ma ọ bụ mwepu
Nke mbụ, a na-eme ihe na ntinye aka, ya bụ, a chọtara nchikota ma ọ bụ ọdịiche nke ọnụọgụgụ, mgbe ahụ, a na-eme nkewa.
a: (b-c +d)
b – с + d = e
a: e = f
(b + c – d): a
b + с – d = e
e: a = f
Ntinyeghari
a: (b ⋅ c) =a: b:c =a: c: b (b ⋅ c): a =(b : a) ⋅ p =(ya na : a) ⋅ b
Division
a: (b:c) =(a : b) ⋅ p =(c : b) ⋅ a (b :c): a =b: c: a =b: (a ⋅ c)
atụ:
72: (9-8) =72:1 160: (40 ⋅ 4) =160: 40: 4 600: (300: 2) =(600:300) ⋅ 2
