Question

575:23+15*34 ,(2884+1508):122-22,34*25-11*12,(237-182)*23-13

Answer 1

1)25+510=535
2)4392/122-22=36-22=14
3)850-132=718
4)55*23-13=1265-131252

Answer 2

575:23=25
15*34=510
25+510=535


2884+1508= 4392
122-22=100
4392:100=43,92


34*25= 850
11*12= 132
850-132= 718

237-182= 55
55*23= 1265
1265-13=1252

Answer 3

Let's solve each of these expressions step by step:

1. 575:23 + 15 * 34

   • First, divide 575 by 23: 575 / 23 = 25
   • Then, multiply 15 by 34: 15 * 34 = 510
   • Finally, add the results: 25 + 510 = 535

2. (2884 + 1508):122 - 22

   • First, add 2884 and 1508: 2884 + 1508 = 4392
   • Then, divide the sum by 122: 4392 / 122 = 36
   • Finally, subtract 22: 36 - 22 = 14

3. 34 * 25 - 11 * 12

   • Multiply 34 by 25: 34 * 25 = 850
   • Multiply 11 by 12: 11 * 12 = 132
   • Subtract the second result from the first: 850 - 132 = 718

4. (237 - 182) * 23 - 13

   • Subtract 182 from 237: 237 - 182 = 55
   • Multiply the result by 23: 55 * 23 = 1265
   • Finally, subtract 13: 1265 - 13 = 1252

So, the results of the given expressions are:

1. 575:23 + 15 * 34 = 535
2. (2884 + 1508):122 - 22 = 14
3. 34 * 25 - 11 * 12 = 718
4. (237 - 182) * 23 - 13 = 1252
