1. Realiza las siguientes operaciones con varios números enteros. (a) \( -3+8-12+5+9-10= \) \( ( \) b \( )+15-13-2-8-11+21+34= \) \( ( \) c \( )-11-6-8+19+24+32-41= \) \( (d)-3-12-42-51+27+17+6-1= \) \( (e)-35+24+7-8-30-29+50= \) \( (f)+4+16-15-1-4+10-7-3= \) \( (g)-8-11+10+9+13-15-7= \) \( (h)+15+6+32+70-43-19-56+2= \) (i) \( -1-2+12+7+72-35-20+10= \) \( (j)-8+5+76+90+12+104= \)

1- \( 4-\frac{7}{8}+\frac{1}{12}= \)

D) \( \frac{10}{6}+\frac{4}{5}= \)

\( 9 \times 3 - [ 28 - \{ 12 \div ( 10 - \overline { 6 - 2 } ) \} ] \)

List the given numbers in order from least to greatest. \( -5.3,\left|-4 \frac{1}{4}\right|, 0,-12.5,|-1.7|, 6.3 \) Choose the correct order. A. \( -12.5,-5.3,0,|-1.7|,\left|-4 \frac{1}{4}\right|, 6.3 \) B. \( |-1.7|,\left|-4 \frac{1}{4}\right|,-5.3,-12.5,0,6.3 \) C. \( -5.3,-12.5,0,|-1.7|,\left|-4 \frac{1}{4}\right|, 6.3 \) D. \( -12.5,-5.3,\left|-4 \frac{1}{4}\right|,|-1.7|, 0,6.3 \)

f) \( \sqrt{25}+2 \times 3^{2}= \) g) \( 9-2 \times 6^{2}= \) h) \( 50 \div 10+50 \div 2= \) i) \( 12-6^{2} \div 9= \) J) \( 60 \div 5-3 \times 2= \)
