Question

Can you solve this
By using 1,2,3 4,5, and 6.
1. All numbers are to be used.
2. Use above numbers only once (no repetition) .
3. Nothing can be written other than given numbers.
++=90

Answer 1

1+2+3+4+5=15x6=90.

Explanation:

• To get 90 we will add the first five numbers, first:

• 1+2+3+4+5=? and 6

• When we add these we will get 15 and 6.

• Now we have two number and we have to get 90 from these two values.

• Now adding six into fifteen won't work so we will multiply both these values then we will get 90.

• 15x6=90

Answer 2

Nice question:

• 1) Let's add the numbers 1 to 5.

• 2) Then multiple the answer with 6.

Given numbers:

• 1, 2, 3, 4, 5, 6

Adding numbers 1 - 5:

• 1 + 2 + 3 + 4 + 5

Answer we get:

• 1 + 2 + 3 + 4 + 4 = 15

Multiplying answer with 6:

• 15 × 6 = 90

Hence done as per the given question.
