cum se rezova 500-[(16•18-198:f):7+14•5+10]:4•7+5=299

Answer 1

500-[(16•18-198:f):7+14•5+10]:4•7+5=299

[(288-198:f):7+70+10]:4×7+5 = 500-299

[(288-198:f):7+80]:4×7+5 = 201

[(288-198:f):7+80]:4×7=201-5

[(288-198:f):7+80]:4×7 = 196

[(288-198:f):7+80]:4=196:7

[(288-198:f):7+80]:4 = 28

(288-198:f):7+80 =28×4

(288-198:f):7+80 = 112

(288-198:f):7 = 112 -80

(288-198:f):7 = 32

288-198:f = 32×7

288-198:f = 224

198:f = 288-224

198:f = 64

f = 198/64

f = 99/32
