Answer 1

Explicação passo-a-passo:

180+35×2÷7-20

180+70÷7-20

180+10-20

190-20

170

100+[12-(120÷30)×3]-99

100+[12-4×3]-99

100+[12-12]-99

100+0-99

100-99

240-{120÷[(5×8÷2)+124]+8×3}

240-{120÷[(40÷2)+124]+8×3}

240-{120÷[20+124]+8×3}

240-{120÷144+8×3}

240-{0,83+8×3}

240-{0,83+24}

240-24,83

215,17
