A) 5 x 12-8= 60 - 8 = 52 b) (23+41):2= 64:2= 32 c) 3 x (9 x 3-10)=3 x 17 = 51 d) (26-18) x (3+7)= 8 x 10 = 80 e) (5+8) x 2+2 x 7=13 x 2 + 14 = 26 + 14 = 40 f) 72:9-(32-24)=8 - 8 = 0
b) (23+41):2=64:2=32
c) 3x(9x3-10)=3*(27-10)=3*17=51
d) (26-18)x(3+7)=8*(3+7)=8*10=80
e) (5+8)x2+2x7=13*2+2*7=26+14=40
f) 72:9-(32-24)=8-(32-24)=8-8=0
b) (23+41):2= 64:2= 32
c) 3 x (9 x 3-10)=3 x 17 = 51
d) (26-18) x (3+7)= 8 x 10 = 80
e) (5+8) x 2+2 x 7=13 x 2 + 14 = 26 + 14 = 40
f) 72:9-(32-24)=8 - 8 = 0
Proszę bardzo ;3
