-
- 137 becomes 731
276 becomes 672
so 435 becomes 534 - 9 years agoHelpfull: Yes(19) No(6)
- Its a base 8 addition so ans is 1623
- 9 years agoHelpfull: Yes(11) No(0)
- 534..no mathematical logic to it
- 9 years agoHelpfull: Yes(5) No(4)
- it is base 8 addition 137+276, unit digit 7+6=13 which is written as 15,3+7+1=11 written as 13 then 1+2+1=4 written as it is . so same way in 731+672 is written as 1+2=3, 3+7=10 written as 12 ,7+6+1=14 written as 16. so the answer is 1623

- 1425
adding the reverse number which is 22//// - 9 years agoHelpfull: Yes(2) No(1)
- 731+672=1403
1403+22=1425 - 9 years agoHelpfull: Yes(2) No(2)
- ans is 534
because
137=731&276=672 then 435=534 - 9 years agoHelpfull: Yes(1) No(1)
- it's 8 base addition
in general addition
731+672=1403
but in 8 base addition ans is 731+672=1623

- 6+7 = 13 (base 10) which is 15 (base 8). So write down a 5 and carry the one.
3+7+1 = 11 (base 10), which is 13 (base 8). Write down a 3 and carry the one.
1+2+1=4.
So 137 (base 8) + 276 (base 8) = 435 (base 8). So far so good!
Now do the other addition base 8:
1+2=3, so the last digit is 3
3+7=10 (base 10) = 12 (base 8), so the next digit is 2. Carry the 1.
7+6+1 = 14 (base 10) = 16 (base 8).
So our answer is 1623 (base 8) - 8 years agoHelpfull: Yes(1) No(0)
- 534 logically
- 9 years agoHelpfull: Yes(0) No(2)
- it is base 8 addition.
so 1623 is write answer. - 9 years agoHelpfull: Yes(0) No(0)
- 1425.731 + 672 = 1403.So 1403 + 22 = 1425

- 534..just by reversing digit of first equation.
- 9 years agoHelpfull: Yes(0) No(0)
- logically 534
- 9 years agoHelpfull: Yes(0) No(0)
- 534
276 is reverse of 672
731 is reverse of 137 - 9 years agoHelpfull: Yes(0) No(0)
- 137+276=413 so 435-413=22
now 731+672=1403 so 1403-22=1381 - 9 years agoHelpfull: Yes(0) No(0)
- Octal addition so 1623
- 7 years agoHelpfull: Yes(0) No(0)
- Now converting 731 and 672 in decimal
7×8^2 + 3×8^1 + 1×8^0 = 473
6×8^2 + 7×8^1 + 2×8^0 = 442
Adding 473 + 442 = 915
Converting 915 into base 8 = 1623 - 5 years agoHelpfull: Yes(0) No(0)
