Question

29²+35²+33²+31²-34²-32²-30²-28²=?

Answer 1

#29^2+35^2+33^2+31^2-34^2-32^2-30^2-28^2 =252#

Explanation:

• In order to solve this question, we must first consider the value of each of the square numbers. This is done in the following way:
  `(29*29)+(35*35)+(33*33)+(31*31)-(34*34)-(32*32)-(30*30)-(28*28)`
• We then carry out the multiplication to solve each for each multiplication. This is done in the following way:
  `(841)+(1225)+(1089)+(961)-(1156)-(1024)-(900)-(784)`
• We then carry out the addition and subtraction:
  `(841)+(1225)+(1089)+(961)-(1156)-(1024)-(900)-(784)=252`
