Question

La 1, 2, 3 va rog:) dau coroana

Answer 1

Răspuns:

1) b) 1413+1123

2536-4442

6978

c) 2110-1100

2210-1000

3210

(you need to swap them)

2) 2816+4829= 7645

2316-1847= 469

6825-2987= 3838

3) (1804+1216)+(2496+3784)= 9300

(1472+1482)+(2528+4518) =10000

(1999+1998+1997) + (1+2+3) = 6000

Explicație pas cu pas:

1) the main number is at the bottom

(numarul important se afla la inceput, jos)

2) I don't need to explain, you already figured out why

(nu trebuie sa explic, deja ti-ai dat seama)

3) we group it by the first or the last number, in some cases by the level of easiness

(noi grupam numerele dupa primul sau ultimul numar, in niste cazuri dupa nivelul de dificultate)
