Question

27+13 36+14, 34-12 12+12, 42--21 50-20 < > = как решить правельно

Answer 1

27+13<36+14
34-12<12+12                                                                                                                      42-21<50-20

Answer 2

27+13=40 ; 36+14=50 ; 34-12=22 ; 12+12=22 ; 42-21= 21 ; 50-20=30
40<50 ; 40>22 ; 40>21 ; 40>30
50 >40,22,22,30
22=22 ; 22<40 ; 22<30 ; 22<50
21<22,40,50,30
30<40; 30<50 ; 30>22 ; 30>21

Answer 3

To solve the given expressions correctly, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's go through each expression step by step:

1. 27 + 13: Add 27 and 13: 27 + 13 = 40

2. 36 + 14: Add 36 and 14: 36 + 14 = 50

3. 34 - 12: Subtract 12 from 34: 34 - 12 = 22

4. 12 + 12: Add 12 and 12: 12 + 12 = 24

5. 42 - (-21): To subtract a negative number, change it to addition: 42 + 21 = 63

6. 50 - 20: Subtract 20 from 50: 50 - 20 = 30

Now, let's compare the results:

40 < 50 (27 + 13 < 36 + 14) 22 = 24 (34 - 12 = 12 + 12) 63 > 30 (42 - (-21) > 50 - 20)

So, the correct comparisons are: 40 is less than 50, 22 is equal to 24, 63 is greater than 30.

Remember, the "<" sign means "less than," the ">" sign means "greater than," and the "=" sign means "equal to."
