Question

(39000+5300*400):100=? 5400-840*300:10=? 5264:7*30=? 4384:8*50=?

Answer 1

(39000 + 5300 * 400) / 100 = 21590
1) 5300 * 400 = 2120000
2) 2120000 + 39000 = 2159000
3) 2159000 / 100 = 21590

5400-840*300:10= -19800
1) 840 * 300 = 252000
2) 252000 / 10 = 25200
3) 5400 - 25200 =  -19800

5264:7*30 = 22560
1) 5264 / 7 = 752
2) 752 * 30 = 22560

4384 / 8 * 50 = 27400
1) 4384 / 8 = 548
2) 548 * 50 = 27400
