Answer 1

Răspuns:

b = 5687 - 2340 = 3347

c = 1324 + 2315 = 3639

d = 1300 + 345 = 955

e = 6800 - 4500 = 2300

f = 330 - 325 = 5

-g = 2300 - 6500 = - 4200 ; g = 4200

-h = 4326 - 8794 = - 4468 ; h = 4468

Answer 2

Răspuns:

a+560=780

a=780_ 560

a=220

b+2340=5687

b=5687_ 2340

b=3347

c _2315=1324

c=2315+1324

c=9363

d _ 345=1300

d=1300+345

d=1645

4500+e=6800

e=6800 _ 4500

e=2300

325+f=330

f=330_ 325

f=5

6500 _ g=2300

g=6500_ 2300

g=4200

8794 _h =4326

h=8794_ 4326

h=4468
