解答ステップ

300 + 41 - 63 - 56 - 31 + 89 - 114 + 1056

演算のPEMDAS順に従う

足して割る (左から右)

300 + 41 = 341

= 341 - 63 - 56 - 31 + 89 - 114 + 1056

341 - 63 = 278

= 278 - 56 - 31 + 89 - 114 + 1056

278 - 56 = 222

= 222 - 31 + 89 - 114 + 1056

222 - 31 = 191

= 191 + 89 - 114 + 1056

191 + 89 = 280

= 280 - 114 + 1056

280 - 114 = 166

= 166 + 1056

166 + 1056 = 1222

= 1222
