Answer 1

Răspuns:

[(2+200:2)x3+4]x5

[(2+100)x3+4]x5

(102x3+4)x5

(306+4)x5

310x5=1550

[3x10-(5x10x2-8x10)]x25:5

[3x10-(50x2-80)]x5

[3x10-(100-80)]x5

(3x10-20)x5

(30-20)x5

10x5=50

12000-350:5+45:3+[1985-(75:5+24)x35]x15

12000-350:5+45:3+[1985-(15+24)x35]x15

12000-350:5+45:3+(1985-39x35)x15

12000-350:5+45:3+(1985-1365) x15

12000-350:5+45:3+620x15

12000-70+15+9300

12000-85+9300

12000-9385=2615

600+280:4-[680:2+4x(30+12+18)]

600+280:4-[680:2+4x(42+18)]

600+280:4-(680:2+4x60)

600+280:4-(340+240)

600+280:4-580

600+70=580

670-580=90

[(271-169):2+(280+120):4]x2

[(102:2)+(400:4)]x2

(51+100)x2

151x2=302

100x{40+10x[6+10x(62+62:2)]}

100x{40+10x[6+10x(62+31)]}

100x[40+10x(6+10x83)]

100x[40+10x(6x830)]

100x(40+10x4980)

100x(40+49800)

100x49840=498400

24x{100:[412-(317+90)]}

24x[100:(412-407)

24x(100:5)

24:20=480

{100-[99+999-(1000-1)]:9}:89

[100-(99+999-999):9]:89

[100-(99+0):9]:89

(100-99:9):89

(100-11):89

89:89=1
