Calculati:
4+ 5x{36:9+0x10+ 3 X (330:5-72:2)]} =
20+2 x {32:8+4 x [20+4 x (800:5-36:2)]} =
150+ {450:5+25:5 x [975-(50:5+3)x75]} x 2 =​

Answer 1

4+5×{36:9+0×[10+3×(330:5-72:2)]}

4+5×{4+0×[10+3×(66-36)]}

4+5×[4+0×(10+3×30)]

4+5×[4+0×(10+90)]

4+5×(4+0×100)

4+5×(4+0)

4+5×4

4+20

24

20+2×{32:8+4×[20+4×(800:5-36:2)]}

20+2×{4+4×[20+4×(160-18)

20+2×[4+4×(20+4×142)

20+2×[4+4×(20+568)

20+2×(4+4×588)

20+2×(4+2352)

20+2×2356

20+4712

4732

150+{450:5+25:5×[975-(50:5+3)×75]}×2

150+{90+5×[975-(10+3)×75]}×2

150+[95×(975-13×75)]×2

150+[95×(975-975)]×2

150+(95×0)×2

150+0×2

150+0
