    138. 6 multiplied by 25 (5 squared) equals 150. 150 minus 20 (4 times five) is 130. 130 plus 8 equals 138

    138, because we do order of operations and because there are no paranthese's we do exponents first like so, 5²=25 then 6*25=150 then 150 - (4*-5=-20) so 150-20=130 then 130+8=138=) Enjoy!=)
