Question

a) 101- [(45 : 9 x 10) + (39 : 13 + 47)] =
b) {[37 - (6 x 5 + 1)] : 3 + 4} =
c) 320 : [(120 - 10 x 9) + (10 + 5 x 8)] =
d) 180 + {2 x [5 x 3 + (8 x 6 - 2 x 9) - (19 x 3 - 37)]} =

Answer 1

a- 101-[(45:9x10)+(39:13+47)]
101-[(5x10)+(3+47)]
101[50+50]
101-100= 1
b-{[37-(6x5+1)];3+4}
{37-(30+1)];3+4}
{37-31];3+4}
{6:3+4}
2+4= 6
c-320:[(120-10x9)+(10+5x8]
320;[(120-90)+(10+40]
320:[30+50]
320:80= 40
d-180+{2x[5x3+(8x6-2x9)-(19x3-37)]}
180+{2x[15+(48-18)-(57-37)]}
180+{2x[15+30-20]}
180+{2x[45-20]}
180+{2x25}
180+50= 230
