9 - 26 got -17
-4 - 15 i got : -19
21 - (-7) i got: 28
27 - (-16) i got: 43
-16 - (-43) i got 59
47 - 19 i got : 28
-156 -98 i got : -58
-192 -47 i got: -145
0 - (-51) = 51
-16- (-43)=-16+43=17
-156-98=-254
-192-47=-239
was my answers correct?
These are wrong:
-16 - (-43) i got 59
-156 -98 i got : -58
-192 -47 i got: -145
The others are correct.
-16 - (-43) i got
-16 + (43) = 27
-156 - 98 i got
-156 + 98 = -254
-192 - 47 i got
-192 + -47 = -239
0 - (-51) i got
o + 51 = 51
-63 -89 i got
-63 + -89 = 152
-12 - (-21) i got
-12 + 21 = 9
92 - (-16) i got
92 + 16 = 108
72 - 15 i got
72 + -15 = 57
-86 - (-19) i got
-86 + 19 = 67
17 - (-46) i got
17 + 46 = 63
-78 - (-53) i got
-78 + 53 = -25
did i get these right?
To solve these subtraction problems, you can follow the steps below:
1. Start by identifying the two numbers being subtracted.
2. For each problem, subtract the second number from the first number.
3. Check the sign of the second number. If it is positive, subtract it normally. If it is negative, change the subtraction sign to an addition sign and change the sign of the second number. This is because subtracting a negative number is the same as adding its positive counterpart.
4. Perform the subtraction operation and record the resulting answer.
Now let's solve the problems one by one:
1. 9 - 26:
Subtract 26 from 9: 9 - 26 = -17
2. -4 - 15:
Subtract 15 from -4: -4 - 15 = -19
3. 21 - (-7):
Change the subtraction to an addition since we have a negative number: 21 + 7 = 28
4. 27 - (-16):
Change the subtraction to an addition: 27 + 16 = 43
5. -16 - (-43):
Change the subtraction to an addition: -16 + 43 = 27
6. 47 - 19:
Subtract 19 from 47: 47 - 19 = 28
7. -156 - 98:
Subtract 98 from -156: -156 - 98 = -254
8. -192 - 47:
Subtract 47 from -192: -192 - 47 = -239
9. 0 - (-51):
Change the subtraction to an addition: 0 + 51 = 51
