Answer 1

$| -10| = 10 \ \ si \ \ |+10|= 10$

a)

$- 25+|-12|+|-8|+(10) = - 25+12+8+10 = 30 - 25 = 5$

b)

$+17+|+6|+|-15|+(-20) = 17+6+15-20 = 38-20 =\bf 18$

c)

$-4+|+6+(-11)|+|-15+12|+(-18) = -4+|+6-11|+|-3|-18 = -4+|-5|+3-18 = -4+5+3-18 = 8-22 =\bf -14$

d)

$|1+(-9)|+|3+(-15)+6|+(-8) = |1-9|+|3-15+6|-8 = |-8|+|-6|-8 = 8 + 6 - 8 =\bf 6$

e)

$|+26+(-15)+(-14)|+|-21+12| = |26-15-14|+|-9| = |-3| + 9 = 3 + 9 =\bf 12$

f)

$-7+|-12+12|+|-7|+(+14) = -7+|0|+7+14 = 21-7 =\bf 14$
