CALCULATI RESPECTAND REGULILE; a) 90+{(42-34)x(72:6-7)}:10= b) {(83-59):3+57:3+6x0x7}:9=

Answer 1

90+{(42-34)x(72:6-7)}:10=
90+{8x(12-7)}:10=
90+{8x5}:10=
90+40:10=
90+4=94

{(83-59):3+57:3+6x0x7}:9=
{24:3+19+0}:9=
{8+19}:9=
27:9=3

Answer 2

a 90+{8×(12-7)}:10=
90+(8×5):10=
90+40:10
90+4
=94


b. (24:3+19+0×7):9=
(8+19+0):9
(27+0):9
27:9=3
