Question

53:(37+16):1*8. (63:7+8*6):57. 42:6+0:3+58:1*1. 9*5+9:(67-58)-29

Answer 1

53:(37+16):1•8=8

(63:7+8•6):57=1

42:6+0:3+58:1•1=65

9•5+9:(67-58)-29=17

Answer 2

To solve the given expression, let's break it down step by step:

1. 53:(37+16):18 First, perform the operations inside the parentheses: 37 + 16 = 53 Now the expression becomes: 53:53:18 Perform the division operations from left to right: 53 ÷ 53 = 1 Now the expression becomes: 1:1*8 Finally, perform the multiplication: 1 * 8 = 8 Answer: 8

2. (63:7+8*6):57 First, perform the operations inside the parentheses: 7 + 8 * 6 = 7 + 48 = 55 Now the expression becomes: (63:55):57 Perform the division operation: 63 ÷ 55 ≈ 1.145 Now the expression becomes: 1.145:57 Perform the division operation: 1.145 ÷ 57 ≈ 0.0201 Answer: 0.0201

3. 42:6+0:3+58:11 First, perform the division operations: 42 ÷ 6 = 7 and 58 ÷ 1 = 58 Now the expression becomes: 7 + 0:3 + 581 The colon ":" is often used as a symbol for division, but it seems misplaced in this expression, so let's interpret the expression as: 7 + 0 ÷ 3 + 58 * 1 Perform the division operation: 0 ÷ 3 = 0 Now the expression becomes: 7 + 0 + 58 * 1 Perform the multiplication: 58 * 1 = 58 Finally, perform the addition: 7 + 0 + 58 = 65 Answer: 65

4. 9*5+9:(67-58)-29 First, perform the subtraction inside the parentheses: 67 - 58 = 9 Now the expression becomes: 9 * 5 + 9:9 - 29 Perform the multiplication: 9 * 5 = 45 Now the expression becomes: 45 + 9:9 - 29 Perform the division: 9 ÷ 9 = 1 Now the expression becomes: 45 + 1 - 29 Perform the addition: 45 + 1 = 46 Finally, perform the subtraction: 46 - 29 = 17 Answer: 17

So, the results of the given expressions are:

1. 53:(37+16):1*8 = 8
2. (63:7+8*6):57 = 0.0201
3. 42:6+0:3+58:1*1 = 65
4. 9*5+9:(67-58)-29 = 17
