Answer 1

$(419 + 289) \times 100 - (575 \div 25 + 477) \times 326 \div 10 = \\ = 708 \times 100 - (23 + 477) \times 326 \div 10 = \\ = 70800 - 500 \times 326 \div 10 = \\ = 70800 - 16300 = 54500$

$(152 \div 19 \times 305 - 1040) \div 100 \times 65 + 100090 = \\ = (2440 - 1040) \div 100 \times 65 + 100090 = \\ = 1400 \div 100 \times 65 + 100090 = \\ = 910 + 100090 = 101000$
