Maitiro mune masvomhu

Muchinyorwa chino, tichatarisa mitemo iri mumasvomhu maererano nehurongwa hwemasvomhu anoitwa (kusanganisira mumashoko ane mabhuraketi, kusimudza kune simba kana kubvisa mudzi), tichiiperekedza nemienzaniso yekunzwisisa zviri nani zvinyorwa.

Nzira yekuita zviito

Tinocherechedza pakarepo kuti zviito zvinotaridzirwa kubva pakutanga kwemuenzaniso kusvika pakuguma kwayo, kureva kubva kuruboshwe kuenda kurudyi.

General mutemo

kutanga, kuwanda uye kupatsanura kunoitwa, uyezve kuwedzera nekubvisa kwezvinoguma zvepakati maitiro.

Ngatitarisei muenzaniso zvakadzama: 2 ⋅ 4 + 12 : 3.

Pamusoro pechiito chimwe nechimwe, takanyora nhamba inoenderana nehurongwa hwekuitwa kwayo, kureva mhinduro yemuenzaniso ine matanho matatu epakati:

• 2 ⋅ 4 = 8
• 12:3 = 4
• 8 + 4 = 12

Mushure mekuita zvishoma, mune ramangwana, unogona kuita zviito zvese muketani (mune / mitsetse yakawanda), uchienderera mberi nekutaura kwepakutanga. Muchiitiko chedu, zvinowanzoitika:

2 ⋅ 4 + 12 : 3 = 8 + 4 = 12.

Kana paine kuwanda kwakati wandei uye kupatsanura mumutsara, ivo vanoitwa zvakare mumutsara, uye vanogona kusanganiswa kana zvichidikanwa.

Sarudzo:

• 5 ⋅ 6 : 3 = 10 (kubatanidza nhanho 1 ne2)
• 18:9 = 2
• 7 + 10 = 17
• 17 - 2 = 15

Muenzaniso cheni:

7 + 5 ⋅ 6 : 3 – 18: 9 = 7 + 10 - 2 = 15.

Mienzaniso nemabhuraketi

Zviito mumaparenthesi (kana zviripo) zvinotanga kuitwa. Uye mukati mavo, kurongeka kwakagamuchirwa kwakafanana, kunotsanangurwa pamusoro apa, kunoshanda.

Mhinduro yacho inogona kukamurwa kuita matanho ari pasi apa:

• 7 ⋅ 4 = 28
• 28 - 16 = 12
• 15:3 = 5
• 9:3 = 3
• 5 + 12 = 17
• 17 - 3 = 14

Pakuronga zviito, kutaura kuri mumabhuraketi kunogona kunzwisiswa nemamiriro ezvinhu seinhamba imwe chete/nhamba. Kuti zvive nyore, takazvisimbisa mumaketani ari pazasi mugirini:

15 : 3 + (7 ⋅ 4 - 16) - 9:3 = 5+ 28 - 16 - 3 = 5+ 12 - 3 = 14.

Maparentheses mukati memabhuraketi

Dzimwe nguva panogona kuva nemamwe maparentheses (anonzi nested one) mukati memaparentheses. Muzviitiko zvakadaro, zviito zviri mukati maparentheses anoitwa kutanga.

Kurongeka kwemuenzaniso mumaketani kunoratidzika seizvi:

11 ⋅ 4 + (10 :5 + (16:2 - 12:4)) = 44 + (2+ 8 - 3) = 44 + (2+ 5) = 51.

Exponentiation / midzi kubviswa

Zviito izvi zvinoitwa pekutanga, kureva kuti kunyange tisati tawanza nekupatsanura. Uyezve, kana vane hanya nekutaura kuri mumabhuraketi, ipapo maverengero ari mukati mavo anoitwa kutanga. Chimbofunga muenzaniso:

Nzira:

• 19 - 12 = 7
• 7² = 49
• 6² = 36
• 4 ⋅ 5 = 20
• 36 + 49 = 85
• 85 + 20 = 105

Muenzaniso cheni:

6² + 19 - 12² + 4 ⋅ 5 = 36 + 49 +20 = 105.
