If 137+276=435 how much is 731+672???

• 137 becomes 731
  276 becomes 672
  so 435 becomes 534

• Its a base 8 addition so ans is 1623
• 8 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////
• 8 years agoHelpfull: Yes(2) No(1)
• 731+672=1403
  1403+22=1425
• 8 years agoHelpfull: Yes(2) No(2)
• ans is 534
  because
  137=731&276=672 then 435=534
• 8 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)

• 534..just by reversing digit of first equation.

• 534
  276 is reverse of 672
  731 is reverse of 137
• 8 years agoHelpfull: Yes(0) No(0)
• 137+276=413 so 435-413=22
  now 731+672=1403 so 1403-22=1381

• Octal addition so 1623
• 6 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
