Sum 88 times 98 = 86/24

The deficiencies (12 and 2) have been written above the numbers (on the flag), the minus signs indicating that the numbers are below 100. The answer 8624 is in two parts: 86 and 24.

Q1)  96 x 93  =

Question 2 of 20

3.  

Example : 568 × 998 = 566864

We see here that the numbers 568 and 998 are conveniently close to 1000, so we allow 3 figures on the right. The differences of the numbers from 1000 are 432 and 2.

The method is just the same:  568 – 2 = 566, and 432 × 2 = 864.

857 × 994 =
