1) \(3141306 - 141141 \cdot (5221 + 7084 - 9999) : 141\)
\(5221 + 7084 - 9999 = 12305 - 9999 = 2306\)
\(141141 \cdot 2306 = 325469846\)
\(325469846 : 141 = 2308296.78\) (округлим до 2308297)
\(3141306 - 2308297 = 833009\)
2) \(2029201 - 1029190 : (59030 - 49070 + 230) \cdot 1\)
\(59030 - 49070 + 230 = 9960 + 230 = 10190\)
\(1029190 : 10190 = 101\)
\(101 \cdot 1 = 101\)
\(2029201 - 101 = 2029100\)
