Answer 1

Respuesta:

123. -6

124. -3

125. 25

126. 1

Explicación paso a paso:

123. 3-3×(-1)+5×(-2)-(2) = 3+3-10-2=6-12 = -6

124. -1 ×4-10÷(-2)-8÷2 = -4-10÷-2-8÷2 = -4+5-4 = -3

125. 13-3×[((-1-(-2))×(-2-2)] = 13-3×[((-1+2)×(-4)] = 13-3×[(1×-4)] = 13-3×-4 = 13-(-12) = 25

126. (-2×(-1)+(-2))-(2×(-2)-3×(-1)) = (2+(-2))-(-4)-3) = 4-3 = 1
