MULTIPLY
5 x 5 = ?
2 x 5 = ?
5 x 3 = ?
23 x 3 = ?
3 x 5 x 4 = ?
4 x 100 = ?
12 x 30 = ?
47 x 3 = ?
6 x ? = 12
? x 5 = 20
9 x 2 = ?
6 x 5 = ?
8 x 5 = ?
Use your estimating skills at this level. Estimation is a valuable
tool in mental math. Remember to enter the whole answer.
5 – 2 = ?
6 – 2 = ?
16 – 8 = ?
13 – 8 = ?
5 – 3 = ?
9 – 2 = ?
25 – 4 = ?
654 – 13 = ?
43 – 9 = ?
92 – 58 = ?
170 – 27 = ?
? – 2 = 0
100 – ? = 7
SUBTRACT
Determine the answer “mentally” and enter the whole answer.
Suggestions for mental reminders in multiplying three factors:
• Multiply the first two numbers, then multiply the product by the third.
• Multiply the easier two factors, then multiply the product by the third factor.
