The method of using Repeated Subtraction to find out Square Roots requires you to keep subtracting the given number from odd numbers starting from one(in order) until you get zero. The number of steps you take to get that would be your answer. Let me show you an example:
Square root of 16
It would be:
Step 1: 16 – 1 = 15 (Subtract odd numbers as written above)
Step 2: 15 – 3 = 12
Step 3: 12 – 5 = 7
Step 4: 7 – 7 = 0
The square root of 16 would then be 4, because it had t be subtracted 4 times.
Square root of 16
It would be:
Step 1: 16 – 1 = 15 (Subtract odd numbers as written above)
Step 2: 15 – 3 = 12
Step 3: 12 – 5 = 7
Step 4: 7 – 7 = 0
The square root of 16 would then be 4, because it had t be subtracted 4 times.
