POZIOMO
A) -3*(-13)=39
b)
[tex] \frac{1}{2} | - 920 \div ( - 10)| = \frac{1}{2} \times 92 = 46[/tex]
c)
[tex] |( - 17 \frac{1}{2} + ( - \frac{1}{2} ) | \times | - 17 \frac{1}{2} - ( - \frac{1}{2}) | = ( - 18) \times ( - 17 \frac{1}{2} + \frac{1}{2} ) = - 18 \times ( - 17) = 303[/tex]
H)(-8)*(-9+4)=-8*(-5)=40
I) (-4):(-88)=1/22
odwrotnosc 22/1=22
PIONOWO
A)(-7)*3-(-58)=-21+58=37
C)-21*3=-63
l. przecina to 63
D)36:(-2)*(-4-2)=-18*(-6)=108
f)
[tex]2 \times |15 \frac{1}{2} + ( - 3 \frac{1}{2}) | = 2 \times 12 = 24[/tex]
G)-7*(-6)-10=42-10=32
