Step-by-step explanation:
Multiplying times 7 steps:
Step 1. 8 x 7 = 56
Step 2. 1 x 7 = 7
Step 3. Add the 5 from step 1. 7 + 5 = 12
Step 4. 3 x 7 = 21
Step 5. Add the 1 from step 3. 21 + 1 = 22
Step 6. 1 x 7 = 7
Step 7. Add the 2 from step 5. 7 + 2 = 9
Equals = 9226
Steps for times 6:
Step 1. 6 x 8 = 48
Step 2. 1 x 6 = 6
Step 3. Add the 4 from step 3. 6 + 4 = 10
Step 4. 3 x 6 = 18
Step 5. Add the 1 from step 3. 18 + 1 = 19
Step 6. 1 x 6 = 6
Step 7. Add the 1 from step 5.
Equals = 79080
Now add the two 9226 + 79080 = 88, 306
